%description
Contains functions to perform Bayesian inference using posterior
simulation for a number of statistical models. Most simulation is done in
compiled C++ written in the Scythe Statistical Library Version 1.0.3. All
models return 'coda' mcmc objects that can then be summarized using the
'coda' package. Some useful utility functions such as density functions,
pseudo-random number generators for statistical distributions, a general
purpose Metropolis sampling algorithm, and tools for visualization are
provided.
