Gaussian.deviance(endog, mu, scale=1.0)[source]¶

Gaussian deviance function

Parameters:	endog : array-like Endogenous response variable mu : array-like Fitted mean response variable scale : float, optional An optional scale argument
Returns:	deviance : float The deviance function at (endog,mu) as defined below.

Notes

deviance = sum((endog-mu)**2)
