Continuous time markov chain absorbing state

The twostate chain is the simplest nontrivial, continuoustime Markov chain, but yet this chain illustrates many of the important properties of general continuoustime chains.when it satises two conditions. First, the chain has at least one absorbing state. Second, it is possible to transition from each nonabsorbing state to some absorbing state (perhaps in multiple steps). Consequently, the chain is eventually absorbed into one of these states. 1 This chapter focuses on absorbing Markov chains, developing some special analysis of this type of chain. continuous time markov chain absorbing state

Continuous Time Markov Chains In Chapter 3, we considered stochastic processes that were discrete in both time and space, and that satised the Markov property: the behavior of the future of the process only depends upon the current state and not any of the rest of the past.

Lecture 2: Absorbing states in Markov chains. Mean time to absorption. WrightFisher Model. Moran Model. Antonina Mitrofanova, NYU, department of Computer Science December 18, 2007 1 Higher Order Transition Probabilities Very often we are interested in a probability of going from state i to state j in n steps, which we denote as p(n) ij.

A continuoustime Markov chain (X t) t 0 is defined by a finite or countable state space S, a transition rate matrix Q with dimensions equal to that of the state space and initial probability distribution defined on the state space.

Note that it is not sufficient for a Markov chain to contain an absorbing state (or even several! ) in order for it to be an absorbing Markov chain. It must also have all other states eventually reach an absorbing state with probability 1 1 1. A Markov chain with an absorbing

continuous time Markov chains with diagonal entries of Abeing. Intuitively this means the transition out of a state may be instantaneous. For many Markov chains appearing in the analysis of problems of interest do not allow of instantaneous transitions. We eliminate this possibility by the requirement P[X sh ifor all h [0, ) X s i 1
