WebOct 22, 2024 · A probability distribution describes phenomena that are influenced by random processes: naturally occurring random processes; or uncertainties caused by incomplete knowledge. The outcomes of a random process are called a random variable, X. The distribution function maps probabilities to the occurrences of X.

WebThis paper studies the goodness of fit test for the bivariate Hermite distribution. Specifically, we propose and study a Cramér–von Mises-type test based on the empirical probability generation function. The bootstrap can be used to consistently estimate the null distribution of the test statistics. A simulation study investigates the goodness of the …
