-
Probit.jac(*args, **kwds)
-
Probit model Jacobian for each observationjac
is deprecated, usescore_obs
instead! Use score_obs method. jac will be removed in 0.7Parameters: 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
for observations
Where . This simplification comes from the fact that the normal distribution is symmetric.
