Poisson.jac()
statsmodels.discrete.discrete_model.Poisson.jac
-
Poisson.jac(*args, **kwds)
-
Poisson model Jacobian of the log-likelihood 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: score : ndarray (nobs, k_vars)
The score vector of the model evaluated at
params
Notes
for observations
where the loglinear model is assumed
