Count data often show a higher incidence of zero counts than would be expected if the data were Poisson distributed. Zero-inflated Poisson regression models are a useful class of models for such data, ...

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 ...

The Poisson distribution is widely used in artificial intelligence (AI) and machine learning. In Bayesian inference, probability distributions often help solve problems that would otherwise be ...

The two-parameter Poisson-Dirichlet distribution, denoted PD (α, θ), is a probability distribution on the set of decreasing positive sequences with sum 1. The usual Poisson-Dirichlet distribution with ...

The study integrates Gaussian copula and shifted-gamma copula (factor decomposition) models into the Poisson binomial distribution framework, enabling the valuation of credit portfolios with tranches ...

A discrete distribution is a statistical probability distribution that represents the possible discrete values a variable can take.
