WebSo a Markov chain is a sequence of random variables such that for any n;X n+1 is condi-tionally independent of X 0;:::;X n 1 given X n. We use PfX n+1 = jkX n= ig= P(i;j) where i;j2E is independent of n. The probabilities P(i;j) are called the transition probabilities for the Markov chain X. The Markov Chain is said to be time homogenous. WebUnderstanding the "first step analysis" of absorbing Markov chains.
