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 ... Webchain starts in a generic state at time zero and moves from a state to another by steps. Let pij be the probability that a chain currently in state si moves to state sj at the next step. The key characteristic of DTMC processes is that pij does not depend upon the previous state in the chain. The probability

WebA Markov chain is a stochastic process, but it differs from a general stochastic process in that a Markov chain must be "memory-less."That is, (the probability of) future actions are not dependent upon the steps that … simply alex jean
