Logit.score(params)[source]

Logit model score (gradient) vector of the log-likelihood

Parameters:

params: array-like :

The parameters of the model

Returns:

score : ndarray, 1-D

The score vector of the model, i.e. the first derivative of the loglikelihood function, evaluated at params

Notes

\frac{\partial\ln L}{\partial\beta}=\sum_{i=1}^{n}\left(y_{i}-\Lambda_{i}\right)x_{i}
