WebA canonical reference on Markov chains is Norris (1997). We will begin by discussing Markov chains. In Lectures 2 & 3 we will discuss discrete-time Markov chains, and Lecture 4 will cover continuous-time Markov chains. 2.1 Setup and definitions We consider a discrete-time, discrete space stochastic process which we write as X(t) = X t, for t ... WebIn other words, a coupling consists of two copies of the Markov chain M running simultaneously. These two copies are not literal copies; the two chains are not …
WebMarkov Chains and Coupling In this class we will consider the problem of bounding the time taken by a Markov chain to reach the stationary distribution. We will do so using … WebJun 12, 2024 · This article draws connections between unbiased estimators constructed from coupled Markov chains that meet exactly after a random number of iterations, and solutions of the Poisson equation. We first show how such pairs of chains can be employed to obtain unbiased estimators of pointwise evaluations of solutions of the Poisson equation.
