# Ethical Data Science

As data science has evolved into AI, the intimate connection between the scientist and the data is growing distant. As black-box models, with their superior predictive power, increasingly dominate, the modeler’s ability to recognize and avoid harmful and even illegal […]

# Word of the Week

## Squashing Function

In logistic regression, a squashing function takes the output of a logit model, which produces odds, and “squashes” it so that it fits in the range between 0 and 1 and can be interpreted as a probability.

## Joseph Hilbe

Joseph Hilbe, a prolific author in the field of statistical modeling, taught a number of Statistics.com courses right up until his death, just over 3 years ago. In addition to his numerous contributions in statistics, Joe had an abiding interest in astrostatistics and would happily show any visitor his treasured collection of […]

# Course Spotlights

## Logistic Regression (July 17 – Aug 14)

Developed by Joseph Hilbe and now taught by James Hardin, this course covers:

• How to specify when a logistic regression model is used, and its form
• How to fit a logistic model
• Using information criteria to assess model performance
• Dealing with risk factors, confounders, effect modifiers, interactions
• Dealing with excessive dispersion

## Spatial Statistics for GIS Using R (July 10 – Aug 7)

In this course, you will learn how to:

• Describe spatial data using maps
• Describe and implement the ways spatial data is represented in R
• Use spastat to analyze patterns in point data, and detect non-randomness
• Use spdep to analyze patterns in area data, and measure spatial autocorrelation in lattice data
• Use gstat to analyze continuous field data and create contour maps

Your instructor is Prof. Dave Unwin, co-author of Geographic Information Analysis (Wiley), and a variety of other books on this topic.
