How to know if a markov chain is regular
http://www3.govst.edu/kriordan/files/ssc/math161/pdf/Chapter10ppt.pdf 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.

WebWe know that if a (finite state space) Markov Chain is aperiodic, then there is some $n_0$ s.t. for all $n\ge n_0$ and all states $i$, $p_{ii}^n>0$. WebMARKOV CHAINS Definition: Let P be an n×nstochastic matrix.Then P is regular if some matrix power 𝑃 contains no zero entries. Theorem 1: (Markov chains) If P be an n×nregular stochastic matrix, then P has a unique steady-state vector q that is a probability vector. Furthermore, if is any initial state and =𝑷 or equivalently =𝑷 −

Web7 feb. 2024 · Since the Markov chain is regular, there exists a k such that for all states i, j in the state space P k ( i, j) > 0. Naturally, a regular Markov chain is then irreducible. Now, since P k > 0 for all i, j, then P k + 1 has entries π i j k + 1 = ∑ t π i t π t j k > 0, since for at least one t, π i t > 0. Web17 jul. 2024 · One type of Markov chains that do reach a state of equilibrium are called regular Markov chains. A Markov chain is said to be a regular Markov chain if some power of its transition matrix T has only positive entries. 10.3.1: Regular Markov Chains (Exercises) 10.4: Absorbing Markov Chains
WebBoth sources state a set of states C of a Markov Chain is a communicating class if all states in C communicate. However, for two states, i and j, to communicate, it is only necessary that there exists n > 0 and n ′ > 0 such that. It is not necessary that n = n ′ = 1 as stated by @Varunicarus. As you mentioned, this Markov chain is indeed ...
