OrdinalGEE.mean_deriv(exog, lin_pred)

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.
