Webchain: Proposition 1.1 For each Markov chain, there exists a unique decomposition of the state space Sinto a sequence of disjoint subsets C 1,C 2,..., S= ∪∞ i=1C i, in which each subset has the property that all states within it communicate. Each such subset is called a communication class of the Markov chain. WebGeneral Decomposition of States A Markov chain is called irreducible if it only has one recurrent class. For any non-irreducible Markov chain, we can identify the recurrent classes using the following process I Create directed edges between any two nodes that have a non-zero transition probability between them.

WebFeb 24, 2024 · First, we say that a Markov chain is irreducible if it is possible to reach any state from any other state (not necessarily in a single time step). If the state space is finite and the chain can be represented by a graph, then we can say that the graph of an irreducible Markov chain is strongly connected (graph theory). grant gustin high schoolWebSo a Markov chain is a sequence of random variables such that for any n;X n+1 is condi-tionally independent of X 0;:::;X n 1 given X n.
