NominalGEE.mean_deriv_exog(exog, params, offset_exposure=None)[source]

Derivative of the expected endog with respect to exog for the multinomial model, used in analyzing marginal effects.

Parameters:
exogarray_like

The exogeneous data at which the derivative is computed, number of rows must be a multiple of ncut.

lprarray_like

The linear predictor values, length must be multiple of ncut.

Returns:
The value of the derivative of the expected endog with respect
to exog.

Notes

offset_exposure must be set at None for the multinomial family.
