Find period of markov chain

WebThis means that, if one of the states in an irreducible Markov Chain is aperiodic, say, then all the remaining states are also aperiodic. Since, p a a ( 1) > 0, by the definition of periodicity, state a is aperiodic. As the given Markov Chain is irreducible, the rest of the states of the Markov Chain are also aperiodic. WebCommunicating classes of a Markov chain are the equivalence classes formed under the relation of mutual reachability. That is, two states are in the same class if and only if each is reachable from the other with nonzero probability in a finite number of steps. ... Class period is the greatest common divisor of the lengths of all cycles ...
