Free Bayesian statistics software

probabilistic programming language for Bayesian inference

JASP is a free and open-source program for statistical analysis supported by the University of Amsterdam. It is designed to be easy to use, and familiar to users of SPSS. It offers standard analysis procedures in both their classical and Bayesian form. JASP generally produces APA style results tables and plots to ease publication. It promotes open science via integration with the Open Science Framework and reproducibility by integrating the analysis settings into the results. The development of JASP is financially supported by sponsors, several universities, and research funds.

GNU MCSim is a suite of simulation software. It allows users to design statistical or simulation models, perform Monte Carlo simulations, and Bayesian inference through (tempered) Markov chain Monte Carlo (MCMC) simulations. The latest version allows parallel computing of Monte Carlo or MCMC simulations.
