Survival probability of a branching process
= Survival probability of a branching process
{title2=$\rho=1-q$}
= Branching survival probability
{synonym}
For a <Galton-Watson process> started from one ancestor, this is the <probability> that every generation is nonempty. It is the complement of the <branching extinction probability>. The <binomial branching survival correction> distinguishes finite-binomial reproduction from the <Poisson branching process> near mean one.
