BEASTObject that performs calculations based on the State.

A class that describes a parametric distribution, that is, a distribution that takes some parameters/valuables as inputs and can produce (cumulative) densities and inverse cumulative densities.

Poisson distribution, used as prior f(k; lambda)=\frac{lambda^k e^{-lambda}}{k!} If the input x is a multidimensional parameter, each of the dimensions is considered as a separate independent component.
