Web7 nov. 2024 · In using the Markov chain Monte Carlo (MCMC) method to reveal posterior distributions in complex big-data Bayesian statistics models, guaranteed success depends on simulating for a number of steps larger than the mixing time, and the mixing time cannot be determined by simulation but requires theory. WebMarkov chain is non-reversible. We will eventually show that a related bound also holds for non-lazy chains. Remark 10.5. Conductance entirely characterizes rapid mixing (mixing in time polynomial in the problem size).
