"""Markov Chain Monte Carlo:
Simulates continuous distributions of random vectors using Markov chain
Monte Carlo (MCMC). Users specify the distribution by an R function that
evaluates the log unnormalized density. Algorithms are random walk
Metropolis algorithm (function metrop), simulated tempering (function
temper), and morphometric random walk Metropolis (Johnson and Geyer, 2012,
<doi:10.1214/12-AOS1048>, function morph.metrop), which achieves geometric
ergodicity by change of variable."""
