# Regression Analysis

This class is all about applying regression analysis and linear models, including generalized linear models, mediation and moderation, with a little bit of machine learning techniques thrown in. The book we’ll use throughout the class, and that drives the structure of the lecture slides, is Regression Analysis and Linear Models by Richard Darlington and Andrew Hayes. This course uses R and RStudio for all data analyses.

We will use several different data sets during the course:

We may also pull from FiveThirtyEight’s open data on GitHub occassionally throughout the class (many of these data sets can be used for your class project as well if they have both continuous and categorical predictors).

### Final Project

Here’s an example of a final project from a few years ago. This follows the template well but doesn’t necessarily have all the stuff in it (e.g., they could have included a DAG, a plot of the data other than the diagnostics), but this shows understanding of the material so it receive a high grade.
