OrdinalGEE.mean_deriv(exog, lin_pred)

Derivative of the expected endog with respect to the parameters.

Parameters

exogarray_like

The exogeneous data at which the derivative is computed.

lin_predarray_like

The values of the linear predictor.

Returns

The value of the derivative of the expected endog with respect

to the parameter vector.

Notes

If there is an offset or exposure, it should be added to lin_pred prior to calling this function.
