statistical distributions
The Poisson distribution is a discrete probability distribution that is often used for a model distribution of count data, such as the number of traffic accidents and the number of phone calls received within a given time period. This entry begins with a definition and description of the properties of the Poisson distribution, which is followed by a discussion of how the Poisson distribution is obtained or estimated.
