+    """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."""
