(Solved): Consider a reversible Markov chain with transition probabilities Pij and limiting probabilities ...
Consider a reversible Markov chain with transition probabilities Pij? and limiting probabilities ?i?. Also consider the same chain truncated to the states 0,1,…,M. That is, the transition probabilities {Pij??} of the truncated chain are Pij??=?????k=0m?Pik?Pij??,0,?0?i,j?M, elsewhere. ? Show that the truncated chain is also reversible and has limiting probabilities given by ??i?=?k=0M??i??m=0M?Pkm??i??j=0M?Pij??
