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

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.
Exponential distribution. f(x;\lambda) = 1/\lambda e^{-x/\lambda}, if x >= 0 If the input x is a multidimensional parameter, each of the dimensions is considered as a separate independent component.
