WebApr 12, 2024 · Assuming if the probability of event at any time point only depends only on the previous state in such stochastic process, a Markov chain is defined. Its most important feature is being memoryless. That is, in a medical condition, the future state of a patient would be only expressed by the current state and is not affected by the previous states, … WebJan 7, 2024 · The transition matrix could be different though. If we want time-symmety, we must begin in an equilibrium of the Markov chain. This is intuitively clear -- else convergence to an equilibrium gives us a clue as to which "direction" of time we're going in. So if X n) is Markov ( λ, P), it is reversible iff P ^ = P, i.e. λ j p j i = λ i p i j.

Webrespectively, and the relaxation time of a reversible Markov chain as ˝ rel(T) = 1 (T): (2) The relaxation time of a reversible Markov chain (approximately) captures its mixing time, which roughly speaking is the smallest nfor which the marginal distribution of X nis close to the Markov chain’s stationary distribution. We refer to [3] for a ... WebSeveral theorems relating these properties to mixing time as well as an example of using these techniques to prove rapid mixing are given. 1 Introduction ... Further, if the Markov chain is reversible then we can conclude that all of its eigenvalues are real.

WebThe hitting time of a Markov chain is the time for a Markov chain to reach a certain state. These values have long been studied such as in problems like gambler’s ruin. More recently, there has been interest in the cover time i.e. the time it takes for a nite Markov chain to hit all of its states.
