# Welcome

Andrew Hayes’s *Introduction to Mediation, Moderation, and Conditional Process Analysis* text, the second edition of which just came out, has become a staple in social science graduate education. Both editions of his text have been from a frequentist OLS perspective. This project is an effort to connect his work with the Bayesian paradigm. Herein I refit his models with my favorite R package for Bayesian regression, Bürkner’s brms. I also prefer plotting with Wickham’s ggplot2, and recently converted to using tidyverse-style syntax (which you might learn about here or here). But to be clear, this project is not meant to stand alone. It’s a supplement to the textbook.

The source code of the project is available here. This project is powered by Yihui Xie’s bookdown package which makes it easy to turn R markdown files into HTML, PDF, and EPUB. You can learn more here. While you’re at it, also check out this great guide to R Markdown.
