statsmodels.discrete.discrete_model.NegativeBinomialP.score_obs

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
