Among the noteworthy updates: * Chapter 1 got an overhaul, and it's now an original introduction to #rstan, with particular focus on the data, parameters, and model blocks 2/4

In Statistical Rethinking 2, Ch 13, @rlmcelreath introduced the centered and non-centered parameterizations for multilevel models. The equations below are based on the tadpoles models in Section 13.1. What would you call this 3rd kind of parameterization? #RStats #rstan

I'm looking for examples simple multilevel models [e.g., y ~ 1 + x + (1 + x | group) in lme4 syntax] coded in Stan/rstan/cmdstanr. Good clean code, the kind you'd recommend for learning. Centered and non-centered parameterization are welcome. #RStats #rstan

2 ways of showing Bayesian uncertainty. Left is the posterior distribution with the mean line in bold, and the thinner lines 100 random HMC draws. The right is the same, but with semitransparent fill for each of the 100 draws. Thoughts? [https://t.co/oJVP4RM5RZ] #RStats #rstan

This book is a side-product of another project for which I needed to learn more about #rstan. I will continue to chip away on this as my schedule permits, but I am setting no goals and no deadlines. 5/5

Relative to my other ebooks, the code and content are sparse. I think #rstan is more advanced than #brms, and therefore I’m presuming a more advanced readership who need less exposition than my usual target audience. The figures and so on are also more streamlined. 2/5

When you define the number of rows in your data in a Stan `data` block, do you set the lower limit to `0` or to `1`? I've seen smart people do it either way. Tell me why or why not. #rstan @mcmc_stan

Don't sweep uncertainty under the rug. Quantify it! The more I build Bayesian models, the more I wonder why anybody would be frequentest anymore. With tools like #mcmc_stan, #rstan, #psytan, etc. things are now really easy (In grad school, we had to code these things from scratch)

For folks setting up #RStan on macOS with newer M1 Pro/Max chips, this post by @patscli is one of the most helpful resources out there for configuring the C++ toolchain and explaining issues/differences related to the new platform architecture. https://t.co/S5JPNvLG4d 1/N

If you are new to using #rstan and have difficulties with getting chains to converge in complex models, take your time to understand certain steps in #HMC sampling and how they are affected by HMC algorithm parameters. It‘s gonna save you time and sweat.
