"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… " - Birth-death process simulation

WebFeb 11, 2024 · The birth-death (BD) process starts with a single infectious individual at the time of origin, t = 0. Infectious individuals “give birth” to new infectious individuals at rate λ, and are removed from the process either through naturally ceasing to be infectious (at rate μ , often called the “death” rate), or through being sampled.
