Logit.score_obs(params)[source]

Logit model Jacobian of the log-likelihood for each observation

Parameters:

params: array-like :

The parameters of the model

Returns:

jac : ndarray, (nobs, k_vars)

The derivative of the loglikelihood for each observation evaluated at params.

Notes

\frac{\partial\ln L_{i}}{\partial\beta}=\left(y_{i}-\Lambda_{i}\right)x_{i}

for observations i=1,...,n
