WebbA Markov chain { X t } on S is a sequence of random variables on S that have the Markov property. This means that, for any date t and any state y ∈ S, (26.1) ¶ P { X t + 1 = y X t } = P { X t + 1 = y X t, X t − 1, …. } In other words, knowing the current state is enough to know probabilities for future states.
