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. A subset of the General Social Survey data set, a data set used in Quas et al. about high risk youth data set, and a data set regarding poverty, violence, and teen birth rates per state will be used in the examples. We will 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).

This is an introduction to statistics at a graduate level (generally PhD students take this course in preparation for further statistical training). Discussion includes topics such as data visualization, exploratory data analysis, and statistical tests (t-tests, ANOVA). This course uses R and RStudio for all data analyses.


  • We are putting together a book that should help with the homework—especially with using R.
  • A PDF with all the formulas we use in the class.
  • A PDF with all the tables we use in the class.
  • A Box Folder that contains nearly all the material used for the class (homework assignments, data, articles).

These are introductory and intermediate graduate R courses for scientists in health, behavioral, social, and educational sciences. The material is taught to be used by very applied individuals with minimal statistical training. The overall goal is to empower reproducible research using R and RMarkdown.

I have lots of material that can be found at: Graduate R Courses–GitHub and Graduate R Courses.

My most recent class material can be found below:


  1. Review of Tidyverse
  2. Tables and Viz’s
  3. Replicable Workflow in R
  4. Basics of Git and GitHub
  5. Creating an R Package
  6. Miscellaneous Topics


  1. Intro to R
  2. Intro to Tidyverse
  3. Exploring Data
  4. Basic Stats
  5. Generalized Linear Models
  6. Multilevel Models
  7. Other Models
  8. Functions, Functions, Functions
  9. More on Visualizations

I will also be using Andrew Heiss’s great walkthrough of replicating Minard’s 1812 plot with ggplot2 (found here).
