WebJan 7, 2024 · The transition matrix could be different though. If we want time-symmety, we must begin in an equilibrium of the Markov chain. This is intuitively clear -- else convergence to an equilibrium gives us a clue as to which "direction" of time we're going in. So if X n) is Markov ( λ, P), it is reversible iff P ^ = P, i.e. λ j p j i = λ i p i j. http://www.stat.yale.edu/~pollard/Courses/251.spring2013/Handouts/Chang-MoreMC.pdf
