# scikits.statsmodels.family.family.InverseGaussian

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.
