Gaussian.deviance(endog, mu, scale=1.0)

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)
