WebExample 6.1.1. Consider a two state continuous time Markov chain. We denote the states by 1 and 2, and assume there can only be transitions between the two states (i.e. we do not allow 1 → 1). Graphically, we have 1 2. Note that if we were to model the dynamics via a discrete time Markov chain, the tansition matrix would simply be P ... WebMarkov chains illustrate many of the important ideas of stochastic processes in an elementary setting. This classical subject is still very much alive, with important …

Webotherwise the Markov chain would have noncommunicating components. The detailed balance condition (4) for this case is f(x)a(x) = f(x+1)c(x+1) . (7) This is one equation for the two unknowns a(x) and c(x+1). In order to have a rapidly mixing chain, we try to choose a(x) and c(x) as close to one as possible consistent with the constraints (5 ...

A “closed” class is one that is impossible to leave, so p ij = 0 if i∈C,j6∈C. ⇒ an irreducible MC has only one class, which is necessarily closed.

Solution: Let p ij, i= 0;1, j= 0;1 be defined by p ij= P[X= i;Y = j]: These four numbers effectively specify the full dependence structure of Xand Y (in other words, they completely determine the distribution of the random vector (X;Y)).
