WebSep 17, 2024 · For a Poisson random variable, the Fisher information (of a single observation) is 1/ λ (the precision or inverse variance). For a sample you have either expected or observed information. For expected … 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 …

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 ...
WebCompound Poisson distribution. In probability theory, a compound Poisson distribution is the probability distribution of the sum of a number of independent identically-distributed random variables, where the number of terms to be added is itself a Poisson-distributed variable. The result can be either a continuous or a discrete distribution .
