NegativeBinomialP.score_obs(params) [source]

Generalized Negative Binomial (NB-P) model score (gradient) vector of the log-likelihood for each observations.

Parameters:	params (array-like) – The parameters of the model
Returns:	score – The score vector of the model, i.e. the first derivative of the loglikelihood function, evaluated at params
Return type:	ndarray, 1-D
