Websystem as a whole. The Markov Chain is the formal tool that can help solving this sort of problems in general. Here we will focus on a specific subset of Markov Chains, the so-called birth–death processes, which well match with the memoryless property of the Poisson process and of the negative exponential distribution. The The birth–death process (or birth-and-death process) is a special case of continuous-time Markov process where the state transitions are of only two types: "births", which increase the state variable by one and "deaths", which decrease the state by one. The model's name comes from a common application, the use of such … See more For recurrence and transience in Markov processes see Section 5.3 from Markov chain. Conditions for recurrence and transience Conditions for recurrence and transience were established by See more Birth–death processes are used in phylodynamics as a prior distribution for phylogenies, i.e. a binary tree in which birth events correspond to branches of the tree and death events correspond to leaf nodes.

WebBecause the birth-death process is assumed to be positive recurrent, the stationary distribution exists and has the following form. π n = 1 c ∏ i = 0 n − 1 λ i ∏ i = 1 n μ i The constant c is given by c = ∑ n = 0 ∞ ∏ i = 0 n − 1 λ i ∏ i = 1 n μ i < + ∞. The summation is finite by the assumption of positive recurrence. WebThe transition rate matrix for a quasi-birth-death process has a tridiagonal block structure where each of B00, B01, B10, A0, A1 and A2 are matrices. [5] The process can be viewed as a two dimensional chain where the block structure are called levels and the intra-block structure phases. [6]
