Web11.1 Convergence to equilibrium. In this section we’re interested in what happens to a Markov chain (Xn) ( X n) in the long-run – that is, when n n tends to infinity. One thing that could happen over time is that the distribution P(Xn = i) P ( X n = i) of the Markov chain could gradually settle down towards some “equilibrium” distribution.

WebIf stationary condition (5.14) of a random process X(t) does not hold for all n but holds for n 5 k, then we say that the process X(t) is stationary to order k. If X(t) is stationary to order 2, then X(t) is said to be wide-sense stationary (WSS) or weak stationary. If X(t) is a WSS random process, then we have 1. E[X(t)] = p (constant) 2. WebIf we define a new stochastic process := for [, +), then the process is called a semi-Markov process. Note the main difference between an MRP and a semi-Markov process is that the former is defined as a two- tuple of states and times, whereas the latter is the actual random process that evolves over time and any realisation of the process has a defined state …

WebThe process is said to be a Feller process, if the space C of all bounded continuous functions on E is invariant under transformations T t ( t ≧ 0) defined by (7). It is proved that if a homogeneous Markov process is of the Feller type and if x ( t, ω) for all ω is a right-continuous function of t, then the process is a strong Markov process.
