Mean first passage time markov chain examples
WebMay 22, 2024 · The first-passage-time probability, fij(n), of a Markov chain is the probability, conditional on X0 = i, that the first subsequent entry to state j occurs at discrete epoch n. That is, fij(1) = Pij and for n ≥ 2, fij(n) = Pr{Xn = j, Xn − 1 ≠ j, Xn − 2 ≠ j, …, X1 ≠ j ∣ X0 = i} Webthe mean first passage times of processes.

WebAug 28, 2024 · The corresponding first passage time distribution is: F(t) = xf − x0 (4πDt3)1 / 2exp[ − (x − x0)2 4Dt] F (t) decays in time as t −3/2, leading to a long tail in the distribution. The mean of this distribution gives the MFPT τ = x2 f / 2D and the most probable passage time is x f2 /6D.
