Initial probability vector

Webb←−Probability that the chain is at state j after n steps State vectors are probability vectors since their entries must sum to 1. The state vector x 0 is called the initial probability vector. Notice that the jth column of P is a probability vector – its entries list the probabilities of a move from state j to the states of the Markov chain. WebbIn addition, if w is the common row vector of W, then we also have wPn = w, for any n ≥ 0. Since the probability of being in x is wx for all times n = 0,1,2,..., the chain is in equilibrium if we start with initial distribution w. Important Fact: Since w is the unique probability vector satisfying x = xP where P is
