An introduction to Markov chains

ample of a Markov chain on a countably infinite state space, but first we want to discuss what kind of restrictions are put on a model by assuming that it is a Markov chain. Within the class of stochastic processes one could say that Markov chains are characterised by …

Example 4.1.1 (Visits to a given state for a Markov chain). Suppose a recurrent finite-state Markov chain with transition matrix [P] starts in state i at time 0. Then on the first return to state i, say at time n, the Markov chain, from time n on, is a probabilistic replica of the chain starting at time 0. That is, the state at time 1 is j ...

Markov Processes - Ohio State University

Markov Processes 1. Introduction Before we give the definition of a Markov process, we will look at an example: Example 1: Suppose that the bus ridership in a city is studied. After examining several years of data, it was found that 30% of the people who regularly ride on buses in a given year do not regularly ride the bus in the next year.
