Fisher information poisson distribution
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. Fisher information In ... The Poisson distribution is a good approximation of the binomial distribution if n is at least 20 and p is smaller than or equal to 0.05, and an excellent approximation if n ≥ 100 and n p ≤ 10.

WebMar 3, 2005 · Summary. The paper discusses the estimation of an unknown population size n.Suppose that an identification mechanism can identify n obs cases. The Horvitz–Thompson estimator of n adjusts this number by the inverse of 1−p 0, where the latter is the probability of not identifying a case.When repeated counts of identifying the … WebIn the last line of your derivation, you substituted the expectation of the Poisson distribution, rather than the expectation of the truncated Poisson distribution. Fix that, and the correct result should follow.
