BEAST v2.5.0 Documentation: beast.math.distributions.ChiSquare

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.
Chi square distribution, f(x; k) = \frac{1}{2^{k/2}Gamma(k/2)} x^{k/2-1} e^{-x/2} If the input x is a multidimensional parameter, each of the dimensions is considered as a separate independent component.

Inputs:

type: beast.core.parameter.IntegerParameter
