GLM.score_factor(params, scale=None) [source]

weights for score for each observation

This can be considered as score residuals.

Parameters:	params (ndarray) – parameter at which score is evaluated scale (None or float) – If scale is None, then the default scale will be calculated. Default scale is defined by self.scaletype and set in fit. If scale is not None, then it is used as a fixed scale.
Returns:	score_factor – A 1d weight vector used in the calculation of the score_obs. The score_obs are obtained by score_factor[:, None] * exog
Return type:	ndarray_1d
