What is Galton-Watson branching process?
The Galton-Watson branching process (or GW-process for short) is the simplest possible model for a population evolving in time. It is based on the assumption that individuals in the population give birth to a number of children independently of each other and all with the same distribution.
Is Galton-Watson a Markov chain?
Then (Zn)n≥0 is called a simple Galton-Watson process or just Galton-Watson process (GWP) with offspring distribution (pn)n≥0 and Z0 ancestors. as a Markov chain on the nonnegative integers with the special transition structure specified by (1.2). Pk((Zn)n≥0 ∈ ·) = P1((Zn)n≥0 ∈ ·)∗k for all k ≥ 0.
How do you calculate extinction probability?
Solution: Let G(s) = E(sY ). The probability of ultimate extinction is γ, where γ is the smallest solution ≥ 0 to the equation G(s) = s. For Y ∼ Binomial(n, p), the PGF is G(s)=(ps + q)n (Chapter 4).
Can a family go extinct?
The process models family names as patrilineal (passed from father to son), while offspring are randomly either male or female, and names become extinct if the family name line dies out (holders of the family name die without male descendants).
What is meant by extinction probability?
Extinction probability is the chance of an inherited trait becoming extinct as a function of time t. If t = ∞ this may be the complement of the chance of becoming a universal trait.
What increases the probability of extinction?
the loss of alleles by genetic drift, increased the probability of population extinction over that expected from de- mographic and environmental stochasticity alone. This demonstrates that the genetic effective population size can strongly affect the probability of population persistence.
What is the probability of ultimate extinction?
For any nontrivial cases (trivial cases are ones in which the probability of having no offspring is zero for every member of the population – in such cases the probability of ultimate extinction is 0), the probability of ultimate extinction equals one if μ ≤ 1 and strictly less than one if μ > 1. ) function.
How do you find the probability of a generating function?
The probability generating function (PGF) of X is GX(s) = E(sX), for all s ∈ R for which the sum converges.
What is a stochastic branching model?
Stochastic branching processes are a classical model for describing random trees, which have applications in numerous fields including biology, physics, and natural language processing. In particular, they have recently been proposed to describe parallel programs with stochastic process creation.
