Score, first derivative of the log-likelihood function
- Parameters:
- params
ndarray Parameter at which score is evaluated.
- scale
float,optional 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.
