GEE.mean_deriv(exog, lin_pred)[source]

Derivative of the expected endog with respect to the parameters.

Parameters:

exog : array-like

The exogeneous data at which the derivative is computed.

lin_pred : array-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.
