How to show something is a markov chain
WebTo show $S_n$ is a Markov chain, you need to show that $$P(S_n=x S_1,\ldots,S_{n-1})=P(S_n=x S_{n-1}).$$ In other words, to determine the transition probability to $S_n$, all you need is $S_{n-1}$ even if you are given the entire past. To do this, write $S_n=S_{n … WebDe nition 1.1 A positive recurrent Markov chain with transition matrix P and stationary distribution ˇis called time reversible if the reverse-time stationary Markov chain fX(r) n: n2 Nghas the same distribution as the forward-time stationary Markov chain fX n: n2Ng, that is, if P(r) = P; P i;j(r) = P i;j for all pairs of states i;j ...
