More generally, replacing the Poisson distribution by the richer class of compound Poisson distributions on the non-negative integers, we deﬁne two new “local information quantities,” which, in many ways, play a role analogous to that of the Fisher information for a continuous random variable. We WebDec 1, 2015 · We generated random genealogies, on which mutations were randomly added according to a Poisson distribution with a constant mutation rate. We assumed θ = 4Nμ = 3.0 for each population, where θ is the mutation parameter, N is the population size, and μ is the mutation rate. We drew 500 samples for each of 10 independent replicates. greentech appliance repairs
