Overview

In this course you will learn how to use R to build statistical models and how to use those models to analyze data.Topics include commonly used statistical methods such as multiple regression, logistic regression, the Poisson model for count data and more. This course will cover a variety of techniques, and at different levels, to meet the needs of different groups of users.  The goal is to provide guidance in using R to implement various modeling procedures, not to provide conceptual development of the statistical methods.  Consequently, some knowledge of linear models is required (statistics.com has courses in all of them).

Learning Outcomes

Students who complete this course will learn how to use R to implement various modeling procedures – the emphasis is on the software, not the theoretical background of the models. You will explore linear and logistic regression, generalized linear models, general estimating equations and how to use R to analyze longitudinal data. Most of these modeling techniques are covered in separate courses at Statistics.com.  If you take this course before studying these models you will probably not gain a full understanding of the more advanced techniques, but you will be better positioned, software-wise, to implement them when and if you take those courses.

  • Fit linear regression model
  • Fit logistic regression model
  • Generalize to the generalized linear model
  • Fit Poisson model
  • Fit mixed model to longitudinal data

Who Should Take This Course

Anyone who is familiar with R and wants to learn how to use it to build and use statistical models.

Important
The course covers a variety of techniques and at different levels, to meet the needs of different groups of users.  Those with minimal-to-moderate statistics preparation will want to spend time on the more extensive presentation of linear regression, and not attempt to complete all the more advanced segments on other methods.  Those with more experience in statistics may not require as much time in the early stages, but will be better able to work with the more advanced segments. The goal is to provide guidance in using R to implement various modeling procedures, and not to provide conceptual development of the statistical methods. Most of the modeling techniques described here are covered in separate courses at Statistics.com.

If you take this course first, you will probably not gain a full understanding of the more advanced techniques, but you will be better positioned, software-wise, to implement them when and if you take those courses. If you take the other courses first, you will have a better understanding of the concepts behind the techniques before tackling them in R, but will be less prepared software-wise when you take the conceptual courses. Either approach will work, but each has its own costs and benefits.

What Our Students Say​

I need all the modeling practice I can get in R. I thought this class was very helpful to that end and I plan to take additional courses as a result

Todd Kirschner
Cross Factor Capital

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!
