WebThis proposition implies that for an irreducible Markov chain, either all states are recurrent or they are all transient. Hence, we can classify an irreducible chain as either a recurrent chain or a transient chain. We introduce the following useful lemma from Section 21.2 of [1], which captures the idea for the proof of Proposition 2.3.

WebOct 5, 2024 · Limit distribution of ergodic Markov chains Theorem For an ergodic (i.e., irreducible, aperiodic and positive recurrent) MC, lim n!1P n ij exists and is independent of the initial state i, i.e., ˇ j = lim n!1 Pn ij Furthermore, steady-state probabilities ˇ WebFor this reason, we can refer to a communicating class as a “recurrent class” or a “transient class”. If a Markov chain is irreducible, we can refer to it as a “recurrent Markov chain” or a “transient Markov chain”. Proof. First part. Suppose i ↔ j and i is recurrent. Then, for some n, m we have pij(n), pji(m) > 0. michael wanning polizei borken
