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 an engine for the BUGS language that runs on Unix
* To be extensible, allowing users to write their own functions,
distributions and samplers.
* To be a plaftorm for experimentation with ideas in Bayesian modelling
