Birth and death process examples

WebThere are several standard examples of these birth–death processes. By selecting the birth rate to be constant (α(i) = κ 1, β(i) = 0.), the result is a Poisson process.In population models, these are often used to represent an arrival of an individual to a population from some other population, rather than being generated from the population within.
