GEE.mean_deriv(exog, lin_pred)[source]¶

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.
