TL;DR

The symmetric random-walk Hastings-Metropolis algorithm in situations where the density is not log-concave in the tails is studied, showing that, under mild technical conditions, this algorithm is V-ergodic at a subgeometrical rate.

Abstract

We study the symmetric random-walk Hastings–Metropolis algorithm in situations where the density is not log-concave in the tails. We show that, under mild technical conditions this algorithm is V-ergodic at a subgeometrical rate.
