statsmodels.genmod.generalized_estimating_equations.NominalGEE.score

NominalGEE.score(params, scale=None)

score, first derivative of the loglikelihood function

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 – The first derivative of the loglikelihood function calculated as the sum of score_obs

Return type:

ndarray_1d
