A Poisson distribution is a statistical distribution showing the likely number of times that an event will occur within a specified period of time.

A probability distribution, usually displayed graphically, shows the relative likelihood of all possible outcomes occurring within a specific time period.

The Poisson distribution is a discrete probability distribution. It gives the probability of a certain number of events occurring during a fixed interval. This web calculator allows users to specify ...

Quasi-Likelihood Functions For binomial and Poisson distributions, the scale parameter has a value of 1. The variance of Y is for the binomial distribution and for the Poisson distribution.

Goodness-of-fit tests based on the Cramér-von Mises statistics are given for the Poisson distribution. Power comparisons show that these statistics, particularly A2, give good overall tests of fit.

Ce résultat constitue une extension des travaux de Hodges et LeCam (1960) concernant l'approximation de la distribution binomiale par une Poisson. On présente des applications à la théorie des tests d ...
