The inverse Gaussian distribution, denoted IG(m,f), has probability density function (pdf) d(x;m,f) = 2pfx3 (1/2 exp ˆ x m)2 2fm2x ˙ (1) for x > 0, m > and f > 0. The mean of the distribution is m and the variance is fm3. In generalized linear model theory (McCullagh and Nelder,;Smyth and Verbyla,), f is called the dispersion parameter. The Inverse Gaussian distribution distribution is a continuous probability distribution. The distribution is also called 'normal-inverse Gaussian distribution', and 'normal Inverse' distribution. It is also convenient to provide unity as default for both mean and scale. . The inverse Gaussian is a skew ed, two-parameter continuous distribution whose density is sim- ilar to the Gamma distribution with greater skewness and a sharper peak.

In M.inverse Gaussian distribution with parameters λand µ. An inverse Gaussian random variable X with parameters λand µ has probability density function f(x)= r λ 2πx3 e −λ(x−µ)2 2xµ2 x >0, for λ>0 and µ >0. The inverse Gaussian distribution can be used to model the lifetime of an ob-ject. It has also been used to describe the motion of pollen particles in water and Brownian motion.

The inverse Gaussian is a skew ed, two-parameter continuous distribution whose density is sim- ilar to the Gamma distribution with greater skewness and a sharper peak. The normal inverse Gaussian (NIG) distribution is a recent flexible closed form distribution that may be applied as a model of heavy-tailed processes. The NIG distribution is completely specified.
