As part of my work at MIT, I needed to have a very good understanding of Bayesian statistics, which I have not had much exposure to before. For that reason, I wrote up this document going over some introductory facets of Bayesian statistics. It's very incomplete, of course, but it's a useful tool for brushing up. Here, I am walking through Kruschke's "Doing Bayesian Data Analysis." These are more my notes on the topic than any original lessons.
