Web254 S.TAVARÉ 2. Linear birth-and-death processes Theconstant-ratelinearbirth–deathprocess{Z(t), t≥ 0},withstatespaceS ={0,1,2,...is a classical example of a continuous-time Markov process, in which Z(t)gives the number of individuals in the population at time t.Individuals give birth to a new individual at rate λ>0 and die at rate … WebIn this paper, we introduce the birth/birth-death process, a tractable bivariate extension of the birth-death process, where rates are allowed to be nonlinear. We develop an efficient algorithm to calculate its transition probabilities using a continued fraction representation of their Laplace transforms.

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 models to represent the current size of a population where the transitions are literal births and deaths. Birth–death processes have many applications in de… WebOct 28, 2024 · Birth-death processes have given biologists a model-based framework to answer questions about changes in the birth and death rates of lineages in a phylogenetic tree. Therefore birth-death models are central to macroevolutionary as well as phylodynamic analyses.
