12.7 Discrete-Time Markov Chains

The discrete-time process {Xkk = 0, 1, 2, …} is called a Markov chain if for all ijk, …, m, the following is true:



The quantity pijk is called the state transition probability, which is the conditional probability that the process will be in state j at time k immediately after the next transition, given that it is in state i at time k − 1. A Markov chain that obeys the preceding rule is called a non-homogeneous Markov chain. In this book we will consider only homogeneous Markov chains, which are Markov chains in which pijk = pij. This means that homogeneous Markov ...
