A package with general-purpose MCMC and SMC samplers, as well as plots and diagnostic functions for Bayesian statistics
A package with general-purpose MCMC and SMC samplers, as well as plots and diagnostic functions for Bayesian statistics, particularly for process-based models.
The package contains 2 central functions, createBayesianSetup
, which creates a standardized Bayesian setup with likelihood and priors, and runMCMC
, which allows to run various MCMC and SMC samplers.
The package can of course also be used for general (non-Bayesian) target functions.
To use the package, a first step is to use createBayesianSetup
to create a BayesianSetup, which usually contains prior and likelihood densities, or in general a target function.
Those can be sampled with runMCMC
, which can call a number of general purpose Metropolis sampler, including the Metropolis
that allows to specify various popular Metropolis variants such as adaptive and/or delayed rejection Metropolis; two variants of differential evolution MCMC DE
, DEzs
, two variants of DREAM DREAM
and DREAMzs
, the Twalk
MCMC, and a Sequential Monte Carlo sampler smcSampler
.
The output of runMCMC is of class mcmcSampler / smcSampler if one run is performed, or mcmcSamplerList / smcSamplerList if several sampler are run. Various functions are available for plotting, model comparison (DIC, marginal likelihood), or to use the output as a new prior.
