Abstract

This paper considers ergodicity properties of certain adaptive Markov chain Monte Carlo
(MCMC) algorithms for multidimensional target distributions, in particular Adaptive Metropolis
and Adaptive Metropolis-within-Gibbs. It was previously shown (Roberts and Rosenthal [21])
that Diminishing Adaptation and Containment imply ergodicity of adaptive MCMC. We derive
various sufficient conditions to ensure Containment, and connect the convergence rates of
algorithms with the tail properties of the corresponding target distributions. An example is
given to show that Diminishing Adaptation alone does not imply ergodicity. We also present a
Summable Adaptive Condition which, when satisfied, proves ergodicity more easily.
