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 ... WebA stationary distribution of a Markov chain is a probability distribution that remains unchanged in the Markov chain as time progresses. Typically, it is represented as a row vector \pi π whose entries are probabilities summing to 1 1, and given transition matrix \textbf {P} P, it satisfies. \pi = \pi \textbf {P}. π = πP. howl associates kidderminster
