Web2 J. Pitman and W. Tang where T+ j:=inf{n≥1;Xn =j} is the hitting time of the state j ∈S, and Ei is the expectation relative to the Markov chain (Xn)n∈N starting at i ∈S. It is well known that the irreducible chain (Xn)n∈N has a unique stationary distribution (πj)j∈S which is given by πj =1/mjj for all j ∈S. See, for example, Levin, Peres and Wilmer [67], Chapter 1, or … WebNov 29, 2024 · The mean first passage time in going from state i to statej in a Markov chain is the mean length of time required to go from state t to state./ for the first time. Mean first passage times are useful statistics for analysing the behaviour of various Markovian models of random processes. What is mean first passage time Markov chain?
