I’ve been a Stan user for a few years now, and one thing I’ve always struggled with is how to learn Stan. There is the documentation and the forums, and these are pretty great. But the documentation can be daunting and best suited for those who know for what they seek. So the the learning, for me, from these tend to be scatter-shot and it can be hard to get a clear systematic understanding of the software. I’d always wished there was a Intro to Stan book that could get somebody pretty far and even serve as a bridge to the more technical pieces of the Stan written resources. The best I’ve found is Ben Lambert’s Bayesian textbook. So first I ask, are there any resources about which I am unaware? Next, I thought I might build just such a guide for myself. Here is a rough outline:"
