PyJAGS

Editors note: I am very pleased to announce that Tomasz Mi─ůsko has created a Python interface to JAGS. The rest of this post is by Tomasz.

Nowadays Python users certainly cannot complain about a lack of MCMC packages. We have emcee, PyMC, PyMC3, and PyStan to mention a few. Recently this list was extended by one more; PyJAGS – a Python interface to JAGS. JAGS is a program for analysis of Bayesian hierarchical models using Markov Chain Monte Carlo (MCMC) simulation, quite often used from within the R environment with the help of the rjags package. The PyJAGS package offers Python users a high-level API to JAGS, similar to the one found in rjags. Current rjags users interested in migrating to Python should feel at home. Of course, other interested in doing Bayesian data analysis may also find PyJAGS useful. Continue reading
