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.
