class scikits.statsmodels.family.family.InverseGaussian(link=<scikits.statsmodels.family.links.Power object at 0x01A80ED0>)

InverseGaussian exponential family.

Parameters:

link : a link instance, optional

The default link for the inverse Gaussian family is the inverse squared link. Available links are inverse_squared, inverse, log, and identity. See statsmodels.family.links for more information.

Notes

The inverse Guassian distribution is sometimes referred to in the literature as the wald distribution.

Attributes
