WebSuppose we want to fit a Poisson regression model such that y i ∼ Pois ( μ i) for i = 1, 2 …, n. where: μ i = e β 0 + β 1 x i. The Fisher information can be found by: I ( β) = ∑ i = 1 n μ i x i x i T. Supposing we have the MLEs ( β ^ 0 and β ^ 1) for β 0 and β 1, from the above, we should be able to find the Fisher information ... WebThis paper introduces and studies a new discrete distribution with one parameter that expands the Poisson model, discrete weighted Poisson Lerch transcendental (DWPLT) distribution. Its mathematical and statistical structure showed that some of the basic characteristics and features of the DWPLT model include probability mass function, thew …
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.
