I am once again running two-day courses at the RSS this year:
Introduction to Bayesian Analysis Using Stan , 18-19 April, in-person, London
Introduction to Bayesian Analysis using Stan , 27-28 September, online
Bayesian Meta-Analysis , 11-12 October, online
This year, I am increasing the Gaussian process content in exchange for less time spent on simple regression models. We will have code for rstan and cmdstanr, and I will demo the latter, although you can use the same Stan model code for whatever interface you like, without much effort translating as we go.
