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))
