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