GEE.mean_deriv(exog, lin_pred)[source]

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.
