Geometrically ergodic
WebApr 24, 2005 · Clearly, the chain is geometrically ergodic if and only if ρ * < 1. Establishing the convergence rate of a practically relevant Monte Carlo Markov chain can be quite challenging. Webis assumed to be geometrically ergodic, implying exponential convergence of expecta-tions of functions from a certain class; the general framework of geometric ergodicity within which we operate is taken from the work of Meyn and Tweedie [23, 24] based on Foster-Lyapunov drift conditions. The perturbed Markov chains are assumed to

Webgeometrically ergodic if it converges in total variation and at geometric rate to statistical equilibrium π, with multiplicative constant depending on the starting point: distTV(L(X n),π) ≤ V(X 0)γn (1) for some function V : X→[1,∞) and some rate γ∈(0,1). The chain Xis said to be uniformly ergodic if the function Vcan be chosen to ...
