PoissonUniform equations

 

A PoissonUniform(min,max) is a version of the Poisson (λ) distribution for which the mean λ is itself a Uniform(min,max) random variable:

PoissonUniform(min,max) = Poisson (Uniform (min,max))

Uses

The PoissonUniform distribution can be used in place of the Poisson distribution for modeling counts of events where the observed variation between periods is greater than would be predicted by a Poisson distribution. For a Poisson distribution, Variance/mean is given by:

and for the PoissonUniform it is:

Comments

It can be useful to compare the distribution fits for count data from a variety of Poisson-related distributions like the Poisson, Pólya, Delaporte, ZIPoisson, PoissonUniform and BurntFingerPoisson because they allow you to test different possible mechanisms that may be in place.
