# statsmodels.genmod.generalized_estimating_equations.GEE.mean_deriv_exog¶

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

Derivative of the expected endog with respect to exog.

Parameters: exog (array-like) – Values of the independent variables at which the derivative is calculated. params (array-like) – Parameter values at which the derivative is calculated. offset_exposure (array-like, optional) – Combined offset and exposure. The derivative of the expected endog with respect to exog.
