statsmodels.genmod.generalized_estimating_equations.GEE.mean_deriv_exog

GEE.mean_deriv_exog(exog, params, offset_exposure=None)

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.
