invGauss.density {MixedPoisson}

inverse-Gaussian Density

Description

The function returns the vector of values of density function for of inverse-Gaussian distribution with one parameter \delta.

Usage

invGauss.density(theta, delta)

Arguments

theta

the vector of values

delta

the parameter of inverse-Gaussian distribution

Details

The pdf of inverse-Gaussian is of the form f_\theta(\theta)=\frac{\delta}{2\pi}\exp(\delta^2)\theta^{-\frac{3}{2}} \exp(-\frac{\delta^2}{2}(\frac{1}{\theta}+\theta))

Value

invGauss.density(theta, delta)

the density – the vector of values
