WebWith this definition of stationarity, the statement on page 168 can be retroactively restated as: The limiting distribution of a regular Markov chain is a stationary distribution. If the limiting distribution of a Markov chain is a stationary distribution, then the stationary distribution is unique. Share Cite Improve this answer Follow Web15 dec. 2013 · 4. The idea of memorylessness is fundamental to the success of Markov chains. It does not mean that we don't care about the past. On contrary, it means that …
WebIn probability, a discrete-time Markov chain ( DTMC) is a sequence of random variables, known as a stochastic process, in which the value of the next variable depends only on the value of the current variable, and not any variables in the past. For instance, a machine may have two states, A and E.

(This makes a difference for infinite Markov chains, where we can't necessarily divide by … WebMarkov chains are sequences of random variables (or vectors) that possess the so-called Markov property: given one term in the chain (the present), the subsequent terms (the future) are conditionally independent of the previous terms (the past). This lecture is a roadmap to Markov chains.
