In regression, we are often interested in an interaction, which is the modification of the effect of an independent variable by another. Interactions can be decomposed in three ways, by 1) testing each effect against zero, 2) testing differences among effects, and 3) graphing. This workshop will demonstrate how to do all three analyses in R for the following interaction models: continuous-by-continuous, categorical-by-continuous, and categorical-by-categorical. Some hands-on exercises will be presented. Recommended: Prior knowledge of linear regression and a laptop…

This short course will cover the basics of the Go language for those who already are familiar with an imperative programming environment like Python. The Go programming language (golang) is a simple, high-performance imperative programming language. It has the benefits of a strongly typed, compiled language along with many of the benefits of popular scripting languages like Python. The course will assume familiarity with another imperative language so we can use comparisons (to Python) to leverage familiarity and move quickly.…
