%description
Generates derived parameter(s) from Monte Carlo Markov Chain (MCMC)
samples using R code. This allows Bayesian models to be fitted without the
inclusion of derived parameters which add unnecessary clutter and slow
model fitting. For more information on MCMC samples see Brooks et al.
(2011) <isbn:978-1-4200-7941-8>.
