JAGS
What is JAGS?
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
JAGS is licensed under the GNU General Public License version 2. You
may freely modify and redistribute it under certain conditions (see
