WebThe process is piecewise constant, with jumps that occur at continuous times, as in this example showing the number of people in a lineup, as a function of time (from Dobrow (2016)): The dynamics may still satisfy a continuous version of the Markov property, but they evolve continuously in time.

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. Notably, they are used in viral phylodynamics to … See more • Erlang unit • Queueing theory • Queueing models • Quasi-birth–death process • Moran process See more If a birth-and-death process is ergodic, then there exists steady-state probabilities $${\displaystyle \pi _{k}=\lim _{t\to \infty }p_{k}(t),}$$ See more A pure birth process is a birth–death process where $${\displaystyle \mu _{i}=0}$$ for all $${\displaystyle i\geq 0}$$.
