ll.invGauss {MixedPoisson}

Inverse-Gaussian Log-likelihood

Description

The function returns the value of log-likelihood function for of inverse-Gaussian distribution with one parameter \delta.

Usage

ll.invGauss(delta, t)

Arguments

delta

\delta parameter

t

the vector of values

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
