jags 4.3.1 Gibbs sampler
JAGS is Just Another Gibbs Sampler. It is a program for analysis of Bayesian hierarchical models using Markov Chain Monte Carlo (MCMC) simulation not wholly unlike BUGS. JAGS was written with three aims in mind:
To have a cross-platform engine for the BUGS language;
To be extensible, allowing users to write their own functions, distributions and samplers;
To be a platform for experimentation with ideas in Bayesian modelling.
