%description
Provides a friendly (flexible) Markov Chain Monte Carlo (MCMC) framework
for implementing Metropolis-Hastings algorithm in a modular way allowing
users to specify automatic convergence checker, personalized transition
kernels, and out-of-the-box multiple MCMC chains using parallel computing.
Most of the methods implemented in this package can be found in Brooks et
al. (2011, ISBN 9781420079425). Among the methods included, we have:
Haario (2001) <doi:10.1007/s11222-011-9269-5> Adaptive Metropolis, Vihola
(2012) <doi:10.1007/s11222-011-9269-5> Robust Adaptive Metropolis, and
Thawornwattana et al. (2018) <doi:10.1214/17-BA1084> Mirror transition
kernels.
