Weblater) into state j, and is referred to as a one-step transition probability. The square matrix P = (P ij); i;j2S;is called the one-step transition matrix, and since when leaving state ithe chain must move to one of the states j2S, each row sums to one (e.g., forms a probability distribution): For each i2S X j2S P ij = 1: http://www.columbia.edu/~ks20/stochastic-I/stochastic-I-MCI.pdf

A Markov process is a stochastic process that satisfies the Markov property (sometimes characterized as "memorylessness"). In simpler terms, it is a process for which predictions can be made regarding future outcomes based solely on its present state and—most importantly—such predictions are just as good as the ones that could be made knowing the process's full history.
