### R Package: MCMCpack for Social and Behavioral Sciences Models

Source: https://github.com/cran-task-views/bayesian/blob/main/Bayesian.md

`MCMCpack` offers model-specific Markov chain Monte Carlo (MCMC) algorithms tailored for a wide array of models frequently used in the social and behavioral sciences. It includes R functions to fit various regression models (e.g., linear, logit, ordinal probit, probit, Poisson), measurement models (e.g., item response theory, factor models), changepoint models (e.g., linear regression, binary probit, ordinal probit, Poisson, panel), and models for ecological inference. The package also provides a generic Metropolis sampler, allowing users to fit arbitrary models beyond the predefined set.
