| Parameters: | link : a link instance, optional

|---|
Notes
The inverse Guassian distribution is sometimes referred to in the literature as the wald distribution.
Attributes
| InverseGaussian.link | a link instance | The link function of the inverse Gaussian instance |
| InverseGaussian.variance | varfunc instance | variance is an instance of statsmodels.family.varfuncs.mu_cubed |
