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.

WebAug 1, 2016 · However, I need to simulate continuous time markov chain (CTMC) transition times for birth & death process using C++. I came across this github project which simulates regular CTMC, where the row sum of all lambda will be 1. But in case of birth-death process (M/M/c/K), it will be zero. So I can't exactly use it for my purpose. 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]
