What we’re about

This is a meetup for people interested in Bayesian Statistics, Stan, and related technologies. We'll have talks, Q&A sessions, and workshops.

Stan ( is a probabilistic programming language implementing full Bayesian statistical inference with

• MCMC sampling (NUTS, HMC)

and penalized maximum liklelihood estimation with

•  Optimization (L-BFGS)

Stan is coded in C++ and runs on all major platforms (Linux, Mac, Windows).

Stan is freedom-respecting, open-source software (new BSD core, GPLv3 interfaces)
