Great instructor, TA and peer students. I've really enjoyed this course. Thank you!

-- Hao Song, The National Board of Certification and Recertification for Nurse Anesthetists

This course provided a realistic approach to the analysis of customer
data. The steps involved in the preparation of the data prior to analysis
underscored the need for a solid understanding of the business problem to be
solved and the programming skills required. The R code provided in the course
was terrific especially the use of the tidyverse series of functions and
operators. The course was a strong introduction into that style of programming.
Likewise, with so much of the R code provided it was easier to focus on solving
the business problem.

-- Peter Mulready, System Architect at Boehringer Ingelheim Pharmaceutical

Even though I used to perform sample size calculations before - I was always skeptical of my work and was never confident if I was using the right methodologies.This course has helped me understand when to apply which technique and I can calculate sample sizes much more confidently

-- Suma Krishnaprasad, Cleveland Clinic

I often have to do statistical analysis of the data we collect. Due to my lack of understanding of various statistical procedures, I have always had to depend upon others to tell me which analyses to do and how to interpret those outcomes. I now feel very confident making my choices and most importantly interpreting the outcomes.

-- Jumana Harianawala, Starkey Hearing Technologies

The course notes were very instructive and informative, and very easy to follow along. It was very helpful to know that the instructor was available to answer any and all questions via the discussion board. I feel confident that I can apply the techniques taught in the course to my own work.

-- Bonnie Eklom, James Cook University

I was quite surprised and impressed with the depth of theory development in this area, plus the software options to allow optimum exploration of the data. Thanks for a most interesting course.

-- Daivd Brown, James Cook University

Excellent team. Once again, I'm impressed with the level of interaction that is made almost daily from the instructors and support team. Thank you for all your help.

-- Paula Pelletier-Butler, James Cook University

The course, Introduction to R Programming Part Two, taught by Joris Meys was EXCELLENT!!!All of the course materials were extremely helpful in allowing me not only to understand the details of R programming but also to gain a solid perspective on the fundamentals of R coding. The feedback on the assignments was very detailed and the explanations included why certain approaches of coding were preferable to others. I really enjoyed this course and I learned a great deal.

-- Margaret Palmisano, James Cook University

The material covered here will be indispensable in my work. I can't wait to take other courses. Great work!

-- Benjamin Esterni, Cytel

My statistical knowledge and base continues to increase significantly
now with each additional Statistics.com course taken. While I may not be using
all the learnings directly in my day-to-day work (for example, regression
modeling or calculating sample sizes), they are all influencing how I think
about, approach, and work with data every day; the way in which I describe and
present data and findings to others; and the way in which I interpret other
studies and reports from other researchers, analysts, and statisticians, etc

-- David Plumstead, Cytel

I look forward to taking another course on statistics.com - a great way to continue learning in a structured manner, but flexible enough to participate while Life continues.

-- Brett Berg, Data Manager, Center for Innovative OT Solutions

I found the course to be a valuable introduction to resampling and bootstrapping methods. I am recommending this course to colleagues. Thanks for an engaging and informative course.

As a SAS programmer, I believe I will continue to use SAS for data manipulation but will utilize R when running models and exploring large data sets.

-- Julie Kezik, Yale University

I took the course to get starting using R, thus I think this will help with my use of statistics in the future.   I really think these online courses are great.

-- Pernille Koefoed, University of Copehagen

I need to know R to perform my job as I am a product manager for a software company that interacts with R.  I am now able to understand R scripts and hopefully contribute some of my own. The instructor's videos were great. Just hearing his voice made it more personal. This was my first ever web based course and I really enjoyed it although I had to work hard.

-- Ana Henry, Certara

I will be using this knowledge in my daily work.  Thank you.  It was really interesting and useful.

-- Vladislav Klyashtorny, ZAO Generium

This was one of the best statistics.com courses I've taken.  I'm basing this comment on the online active text and video components - very clear!

-- Silvia Bartolic, Instructor at The University of British Columbia in Sociology

Excellent course!  Great support from Professor and Teaching Assistant!  Loved every single thing about this course and its content.

-- Chafik Abdellaoui, Business Systems Analyst IV at The Coca-Cola Company

-- Jonathan Jenkins, Business Systems Analyst IV at The Coca-Cola Company

More and more medical students are submitting systematic reviews and associated meta-analyses, to meet research exposure requirements, in the Basic Sciences Programs of their medical school education, here in the Caribbean. The course provided me with a unique and much appreciated opportunity to learn much more about the technique, its underlying principles, and how to correctly apply the tool whenever evaluating a collection of primary studies. Time and energies committed to the course have been very well spent.

-- William Keller, Business Systems Analyst IV at The Coca-Cola Company

After trying to learn meta-analysis from various texts (e.g., Hunter et al., 2004; Cooper et al., 2009 and others), I found the Borenstein text and CMA software to be *extremely* user-friendly.  It made the selection of fixed-effect or random-effects models much easier to understand, and the presentation of the math was very straightforward.  If I could write a book, I would want to do it this way.  Each chapter was short and to the point.  Not a lot of extras, but a sufficient number of worked examples to make it work.  The software is very easy to use, and I appreciate the continual improvement that seems to be made.  You and your colleagues have done something incredible here.

-- Chad Briggs, Director of Institutional Research and Effectiveness at Judson University

It will help me gain confidence with conducting data analysis using R.  I have tried a few R MOOCs in the past which helped me start out using R but I had not found a comprehensive intro to R that I could use more broadly - this course really succeeds with accomplishing that.

-- Dalia Estrada-Pintel, Director of Institutional Research and Effectiveness at Judson University

This course has given me a much better understanding of biostatistics and will allow me to gain more from my campus based studies.

-- Leighton Anderson, Director of Institutional Research and Effectiveness at Judson University

THANK YOU. I would recommend that everyone get a copy of the textbook before class though. It complements the ActivEpi CD extremely well.

-- Timothy Berlyn, Holland America Group

This course will greatly contribute to my work as an environmental data scientist and division director.  This course was a great introduction of how to use R to fit the models and how to interpret the R output!

-- Jonathan Jenkins, Holland America Group

Great explanations provided by the course instructor in the videos and on the discussion board.  The Assistant Teacher was very diligent and professional in reaching out to me and giving me every opportunity to be successful in this course!  Definitely a wonderful experience!!!

-- Jonathan Jenkins, Holland America Group

Using information gleaned from the course concerning a not-well-known distance measure (Gower dissimilarity) useful for cluster models that combine data from mixed variables, including nominal, ordinal, and numeric variables, I was able to refine a model I was working on for an academic conference paper.  More broadly, the subject of identifying anomalies is a central task of academic historians, and this course allowed me the welcome luxury to reflect on their nature and methods of discovery.

-- Milan Hejtmanek, Seoul National University

I am now confident that I can use R and continue learning on my own.  The course also helped me to explore other resources within the R community online.  I'm looking forward to using R in data analysis for my masters thesis and beyond.

-- Brooke Eastman, West Virginia University

The two instructors are to be congratulated in putting together a jewel of a short course, one of my very favorite among the many I have taken at Statistics.com.  The discussion with such experts was particularly valuable and greatly enhanced the value of the course.  If there were an extension to this course, I would gladly take it.

-- Milan Hejtmanek, Seoul National University

I felt this class did a good job of reinforcing concepts and their application, and not getting caught up in the algorithms.  The TA feedback was invaluable to me. Thank you!

-- Thomas Higgins, National Science Foundation

There are many things I like about your educational product.  You include variety, such as the videos, the homework, the quizzes, the textbook, and the discussion board.  You have well-thought out curriculum that shows a respect for good pedagogy.  Your instructors are amazing!  They are brilliant, and they respond very quickly!  You apply real-world needs to the material being taught instead of having students memorize formulas or be confined within an academic-only practice of modeling.

-- Jennifer Oesch, National Science Foundation

I realized that I deal with statistics every day. We covered issues that pertain to real life and I now feel I have knowledge about important issues I was previously unaware about.

-- Amelia Feuer, National Science Foundation

I fully enjoyed the challenge of working through the assignments and reading Dr. Pardoe's book. I gained some new insights into regression analysis. In other words, my horizons were expanded and I learned a great deal.

-- Phillip Palmer, Philadelphia College of Osteopathic Medicine

This is the best course so far at statistics.com in terms of assignments and instruction.  Although this is not a Tableau course, Catherine (and evidently Galit) really did a good job of keeping things direct and simple in regards to step by step instructions for getting from point A to B in the Tableau software so the student could follow easily and therefore complete the assignments with confidence.

-- Greg Gazurian, Philadelphia College of Osteopathic Medicine

Your faculty are an incredible asset, making these classes the best learning experience I've had online.

-- Karen Towle, Philadelphia College of Osteopathic Medicine

As always it was a pleasure taking a course from Professor Indurkhya...  This course was a model of what Statistics.com courses can be.

-- Ullash Hazarika, Philadelphia College of Osteopathic Medicine

The professor and assistant instructor were incredibly responsive and helpful.  This was my second Statistics.com class - your faculty are an incredible asset, making these classes the best learning experience I've had online.  (And thank you, thank you, thank you for not *requiring* discussion board participation.  It makes the discussion much more organic, relevant, useful, and enjoyable.

-- Karen Towle, Philadelphia College of Osteopathic Medicine

I understand now what ANOVA is and it seems this is something I can definitely use from time to time for my job tasks.  That's the best to finish a course with the feeling of understanding and getting better in something.  Great course!

-- Arnaud David, Gentian

This course is really a ""dream come true"" for me. In the real sense- This course is at par to what the researchers are working on.

-- Vinuth Tulasi, Juniper Networks

The subject of identifying anomalies is a central task of academic historians, and this course allowed me the welcome luxury to reflect on their nature and methods of discovery.

-- Milan Hejtmanek, Seoul National University

Your faculty/staff have been the most responsive and most helpful of any online classes I've taken.  I also appreciate the incorporation of technology into the Intro Stats program - it's one thing to know the equations... it's another to be able to implement them efficiently and accurately in R, Excel, StatCrunch, etc.  This gives your courses a relevance often lacking in online Intro Stats offerings.

-- Karen Towle, Seoul National University

This is the single most useful course I have ever taken in regards to helping me in the workplace. SQL alone, which I had zero prior experience, is needed for almost every data analytics job I see. R is also ubiquitous and very imporatant. Great to learn how to use both together.

-- Gregory Gazurian, Seoul National University

I am very thankful to the course and assistant teachers. I can only add that the course worth its effort and tuition.

-- Marina Espinasse, Nord University

Absolutely awesome experience. Doing the [exercises] did not feel like homework but it drove home the concepts. Truly wonderful educational experience.

-- David Paget-Brown, Associate Partner in IBM's Strategy and Analytics practice

Professor Babinec did a wonderful job of leading us through this material.  It is obvious that he has a passion for this subject.  His breadth of knowledge of and experience with cluster analysis added significantly to the course.  He gave very helpful answers in the discussion forum!  Anuja, our teaching assistant, was very supportive throughout the course as well.  The course material was challenging but fulfilling, helping us appreciate the subtleties of cluster analysis rather than thoughtlessly plunge ahead.  In summary, this was a very satisfying and useful course.

-- William Barbour, Audi of America through Modis

I am working for Scotiabank/International Banking-Marketing (Toronto-Canada). Since we are manipulating tons of data at the customer level for more than 27 countries, R would be the perfect complement tool (we have been using SAS) for customer analytics. I am new on this R world but I would like to apply it on a daily basis soon.

-- Raul Bauza, Sr. Manager, Global Risk Management - Risk Technology at Scotiabank

The Statistics.com courses have helped me a lot, pushing me to the limit and making me learn much more than I expected I could. The knowledge I gained I could immediately leverage in my job ... then eventually led to landing a job in my dream company - Amazon.

In conjunction with the powerful 'Resampling add-in for Excel' software, resampling methodology seems to be a novel and versatile tool that I expect to frequently use as an adjunct to the more formal established methods of data analysis.

-- David Brown, Data Scientist, NinthDecimal

The tools and understanding gained in this course are absolutely vital to the practice of data analytics (at least to an acceptable standard)... Thank you for a great course. I have learned an incredible amount

-- Timothy Berlyn, Holland America Group

I felt this course helped me "unwrap" another layer of R,  It helped me become a little more comfortable, and less afraid of writing an R program.

-- Douglas Mayfield, Holland America Group

I found this course to be very helpful. It wasn't like other courses where you just run example code and change a few things here and there.  I learned a lot and have even applied what I've learned in this course to the other course I'm enrolled in currently.... Thank you for the great notes and text!

-- Sofia Auer, Data Scientist at National Research Council Canada

The course helped me learn Tableau and some of the effective Visualization techniques. I really liked the detailed assignments with hints and steps required to perform some of the tasks.

-- Ramesh Paskarathas, Data Scientist at National Research Council Canada

The book for this course is very good. Everything is explained in a really clear way. Films are great too and help in understanding issues.

-- Marta Fedyna, Data Analyst, Alta Media

I very much enjoyed the Stats 1 and 2 classes, and I think your book and approach really are excellent.  I have taken a variety of stats-type classes, including calculus-based probability, but the re-sampling gave me a much more intuitive understanding than any other approach.

-- Lily Gadamus, Program Evaluator, Southcentral Foundation

I certainly feel that I got my money's worth from this course and this was almost entirely due to the prompt, thoughtful and expert comments of Brady and Andrzej.

-- Peter Blenis, Professor Emeritus at University of Alberta

-- Eugene Chua, Colby College

I greatly appreciated learning about SEM from a foremost expert of the subject. I now have a more thorough understanding of SEM from theoretical and practical perspectives.

-- Joel Lane, Portland State University

I found this a very good grounding the the statistical theory, but also there were good discussions about some of the practical issues.  The introduction to the various software packages was also very helpful.

-- Jim Pearse, Director, Health Policy Analysis

Every professor has unique and great qualities in them and the unique and great quality that I found in Prof Anthony Babinec is that he can write pages of explanation for each and every line in the book... He is an awesome professor. He explained each and every doubts we had to the perfection.

-- Vinuth Tulasi, Juniper Networks

I feel this class gave me a much better understanding of how to design experiments and enhanced my statistical vocabulary. One thing I liked about Mr. Babinec's approach was that his written explanations were precise. Once I read and comprehended them, they really helped break down what I was reading in the text that was more understandable, especially by comparing/contrasting terms. Overall, I enjoyed the class and it was well worth the time spent.

-- Bryan LeRette, Senior Market Research Analyst - Strategy & Planning, Mosaic Life Care

Instructor John Verzani provided timely and detailed responses to each and every question posted on the forum. His depth of knowledge in both statistics and R and his passion for teaching are the major contribution to the success of this class!

-- Ming Zhang, Senior Statistical Analyst, Northwestern Medicine

I took this class out of general curiosity and the fact that it used Python, which is increasingly attractive to me in building my own software tools.  To my delighted surprise I found the course to be one of the very best (out of more than 20) I have taken at Statistics.com.  It proved a harmonious blend of theory (buttressed by relevant reading and videos by the instructor), focused homework exercises, and training in Python coding.  As a result I learned much and enjoyed the process greatly.  I was particularly impressed with the instructor's choice of homework assignments, which fascinated me, and with the importance he placed in students writing clear, even elegant, Python code.  This is my fifth course using Python at Statistics.com and while I found the other courses quite useful to varying degrees, I never before had an instructor who spent time advising me on the fine details of my actual coding style and suggesting useful improvements.  Allan Leis is a seasoned professional, working in the field, and it was a luxury having him cast an experienced gaze on my rudimentary code.  It's the kind of thing that would never happen in a MOOC and shows the value of a course such as this.

-- Milan Hejtmanek, Seoul National University

This course has been a life/work changer for me. Within 2 weeks of taking this class, I was able to produce far more informative plots than I ever had before. I'm inspired to take more classes and learn as much as I can about this wonderful new world. Regarding Statistics.com in general - based on my experience with this course that is, this is a class act online program. A friend recommended it several years ago, but I opted for free MOOCs instead, which haven't worked for me. The small size of the classes, the attention by the instructor, and the assignments bode well for learning. All in all - a great course!

-- Susan Kamp, Senior Scientist at SM Stoller (U.S. Department of Energy)

It was perfect, much recommended to anybody wanting to understand the dynamics behind political microtargeting and how it can be applied to business. Many theoretical aspects that were known in the past have been empirically implemented with wonderful exercises of Mr. Ken Strasma.

-- Karolis Urbonas, Amazon

I have never had an online class before, and I have typically heard bad things about them, so I was shocked when I found out just how easy this course was to manuever. I really liked the format - it allowed me to work at my own pace yet still check in with the teacher and the other students. A really great experience for my first online course.

-- Kristin Powers, Amazon

Both the instructor and the teaching assistant were approachable, helpful, and knowledgeable about the subject matter, and provided constructive feedback about discussion board posts and assignment submissions.  The textbook will be a valuable resource for future projects.

-- Dennis Fuster, Kremers Urban Pharmaceuticals

-- Vinuth Tulasi, Juniper Networks

All of the courses I have taken through Statistics.com have been excellent in providing understanding of statistical concepts by focusing on the logic and theory behind the equations and formulas, which has allowed me to maximize my learning experience

-- Melissa Brewer, Sage Products

The feedback from assistant teachers was very helpful, and while I was mostly on target, it helped me see where I needed more help.

-- Ryan Holliman, Texas Woman's University

I learned more in the past 6 weeks than I did taking a full semester of statistics in college, and 10 weeks of statistics in graduate school

-- Amir Aminimanizani, MRR Pharmacy Consulting, Inc

I really like the Statistics.com courses. Just before I signed up for the first course, I had tried to work my way through a couple of different textbooks, and just could not get anything out of them. With this class the clear discussion text, relevant assignment problems, and instructor feedback made it easy to learn.  Meena Badade is great at answering student questions with very clear explanations, and Poonam provides excellent feedback on the homework assignments.  Thank you both for a great course!

-- Jim Starcher, MRR Pharmacy Consulting, Inc

Really solid review of early college level statistics, done in a fairly efficient and practical matter with applications that help to solidify one's understanding of the material.  Pleased so far. Good preparatory work for the PASS program.

-- Jeffrey Suchocki, DKOC Enterprises LLC

I now have a better understanding of the foundations of the statistics covered in this module. Although I was familiar with the terms, I now feel more comfortable with discussing the topic!  I think the accompanying course text and the support online has been great. I found the course text easy to follow and the in text examples are a good way to test understanding of what you learn as you work through the text.

-- Samantha Barton, Senior HTA Analyst at BMJ Group

The Instructor, Dave Unwin, was great.  I have to admit that I had my reservations about taking an online course, but I was pleasantly surprised.  Dave obviously put a lot of thought and effort into creating the materials for the course as well as structuring the assignments to give students thoughtful work. He responded to each and every question and was very hands-on.

-- Joleen Beltrami, Department Chair and Associate Professor, University of the Incarnate Word

This was a great class. I learned a lot and enjoyed the format. The lessons, assignments, feedback, and discussions were all informative.  I appreciate Professor Unwin's efforts to include references to web sites, journal articles, and books that will be very useful in the future. Thank you!

Wonderful course... I'll never pass a queue again without thinking more about it :). Dr. Ragsdale's book is superb it’s really clear and whenever I had a question it was only a matter of reading more closely to find the answer

-- Micahel Murphy, Enterprise-Ireland

I was really impressed with how the homework assignments helped me learn the material.  In many stats classes I've taken other places, homework assignments can seem punitive for those who don't understand the material, but this homework seemed to further enhance my learning experience. I would definitely take another class with Dr. Pardoe if I had the opportunity.

-- Ryan Holliman, Texas Woman's University

One of the best classes I've taken with Statistics.com

-- Katie Healey, Ecofish Research Ltd

The course materials are pedagogically well designed. Course administration was efficient. Overall, a pleasant learning experience which is at least as good as any face-to-face course I've attended.

-- Yick Chee Fong, Leibniz-Institute of Freshwater Ecology and Inland Fisheries

Rasch Applications Part 2 is a wonderful follow-up to the first course. Both courses are well designed and build up over the weeks in a such a manner that they make learning new concepts easy to handle

-- Charalambos Kollias, Senior Assessment Officer, Hellenic American University

This course has given me a good understanding of the basics in Rasch analysis. I am very happy that I took this course because I do not think it is possible to just read this kind of information without working with data to get a good understanding of these complex theories and methods.

-- Kaziwe Mollazadegan, St Erik Eye Hospital

The instructor Joris Mays was very effective, especially in the discussion board where his feedback was timely, clear and very thorough

-- Peter Varisco, New York Life Insurance Company

-- Rocio Dominguez Vidana, Baylor College of Medicine

Professor John Verzani is excellent. I used to be thrilled to see his long explanation on the concepts. It was so helpful and makes us love the subject. If you understand the subject, you start loving the subject and this is exactly what I realized and professor's explanation made me start loving R.  Assistant Teacher (Shweta Jadhav) really was so helpful. Her feedback, comments were so very valid and felt really blessed to meet and get taught from such wonderful people.  Every one at Statistics are such wonderful and nice people. I am really blessed to be part of such an institute :)

-- Vinuth Tulasi, Juniper Networks

Both professor Verzani and the TA's were always ready to answer questions. This is probably the most actively I've ever participated in an online class. I really benefitted from this course and I appreciate all the thought and effort put into making it such a valuable resource for R users!

-- Fabiana MacMillan, Rosetta Stone

This course will definitely be used for my work... This course should be called Intro to R for Busy People.   I'm really glad I took this course and will recommend it to others.

-- Kama Kennedy, US Forest Service

Thank you John and the TAs!! You've made my fear of R vanish-- the pace of the course definitely helped with building confidence

-- Richard Coshow, QDNR

This course was tough, but immensely satisfying.  The instructor's lecture notes were written very clearly and were easy to read

-- Alisa Boehme, Statistical Analyst at Walmart Labs

A very nice introduction to Hadoop.  Extremely helpful and I appreciate all the work the instructor put into the course.  I actually benefitted from the lack of Java specific help since I had to generate code on my own... I wasn't able to ""copy / paste"" which is exactly the kind of environment I needed.  I was forced to dig in and found that very rewarding

-- Jeff Crawford, Jackson National Life Insurance Company

I thought the course was well organized and I liked the selected readings and text by Stephen Few

-- Susan Stachler, DePaul University

Visualizing data interactively will be useful when performing any type of data analysis. Dr. Shmueli always answered questions on the discussion forum quickly and very thoroughly.

-- Jorge Medina, DePaul University

I am going to rock the graphics at work! This was an excellent intro to the multiple types of graphics in R, and how and when they can be combined (or not).  This can be very confusing, so this type of intro helps to avoid some of the pitfalls and dead ends. It was a fun and interesting class, with lots of opportunity to create graphics and learn new techniques.

-- Lesley Painchaud, Scientist at US Navy

I will be working a lot creating customized plots and graphics for reports. This class was crucial for my understanding of graphics in R and how to fully customize the output. Thank you so much, this was truly an amazing course and helped out a lot. Well done!

-- Josh Paulson, Investment Analytst, Claragh Mountain Investments LP

It helped me immediately with my job. I was able to understand and apply the concepts to a time-series analysis. The R package I was using (vars) required that I read the documentation, which used much of the terminology and concepts in this class. I would have been quite lost without that introduction to the material. This class really stretched my brain! I loved it!

-- Lesley Painchaud, Scientist at US Navy

The TA was really helpful and very responsive to questions.  Overall the course was a great experience.

-- Marilyn Wheatley, Minitab

-- Peter Mulready, System Architect at Boehringer Ingelheim Pharmaceutical

The theory was clear and well explained; which allowed me to tackle very unfamiliar concepts with relative ease. I feel I now have a really firm foundation on which to build and have been encouraged by this course to keep learning and working towards going even deeper into stats and analysis.

-- Claire Kentler, La Trobe University

The [instructor] was exceptional at answering unclear issues raised and pointing you to right materials to further help your understanding

-- Oluseun Shittu, West London Mental Health NHS Trust

This was a very good course.  Dr. Indrayan has put together a very good on-line learning package.

I really enjoyed this course and found it sufficiently challenging, although well explained and the instructor was very approachable and explained concepts and addressed questions clearly and fairly.  Looking forward to Biostats 2!

-- Claire Kentler, La Trobe University

This was a highly interactive course with a first rank expert in his topic who, fortunately, was also good communicator who likes teaching

-- John Steward, Welsh Cancer Intelligence & Surveillance Unit

This course is well designed and the course materials are simply awesome! The instructor is very knowledgeable in the field and has tons of examples with codes from his website, which is a huge benefit. The focus on programming and practical tips, as opposed to theoretical details, is also a great benefit.

-- Victor Lo, Vice President, Data Science, Fidelity Investments

In a nutshell of the 13 Statistics.com courses I have completed to date, this is one of the top three in the intellectual excitement it generated, and the very best taught of all.  Prof. Sen has created a jewel of a class,packing an entire semester's work into 4 weeks, but doing so with such intelligence, panache, and elegance that I enjoyed every minute of the many hours I devoted to it.  His deft blending of video lectures, outside reading, sample programs, and personal feedback on homework was exemplary.  It would have taken me a whole year to learn this material on my own, if I could have done so at all.  I cannot praise this course highly enough

-- Milan Hejtmanek, Seoul National University

This course will help me handle statistical analyses and related consultancy in a correct, professional and intelligent way.

-- Alfred Keter, Biostatistician, USAID-AMPATH

I came into this course knowing the basics of what Structural Equation Modeling could do. I am leaving this course with a whole new understanding of the ways it can be used to answer many different types of research questions. From psychometrics to multi-level modeling, I now feel like I have a whole new bag of tricks in my tool-belt. While I have read books, being able to go through exercises and get feedback was critical. I do not believe I would have come to such an understanding on my own without this course. It was excellent.

-- Brandi Hinnant-Crawford, Western Carolina University

I am only beginning to use SEM. Without the course I would have lacked the understanding and confidence to try and use SEM. I now feel confident that I could apply one of the models and use the results for work purposes and publication.

-- Celeste Combrinck, Centre for Evaluation and Assessment

This is very good. The explanation is so clear and practical. The problems are very good. They are not too easy nor too difficult, and they are very practical. Those problems help me to apply the skills in the field

-- Yonetaro Kawada, ABeam Consulting

Excellent format, with flexibility to work whenever time is available, and work a bit ahead as needed to work around other committments
