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. Return type:¶ The derivative of the expected endog with respect to exog.
