InverseGaussian.resid_dev()

statsmodels.genmod.families.family.InverseGaussian.resid_dev

InverseGaussian.resid_dev(endog, mu, scale=1.0) [source]

Returns the deviance residuals for the inverse Gaussian family.

Parameters:	endog : array-like Endogenous response variable mu : array-like Fitted mean response variable scale : float, optional An optional argument to divide the residuals by scale
Returns:	resid_dev : array Deviance residuals as defined below

Notes

dev_resid = sign(endog-mu)*sqrt((endog-mu)**2/(endog*mu**2))
