- NominalGEE.mean_deriv(exog, lin_pred)[source]¶
Derivative of the expected endog with respect to the parameters.
- Parameters:
- exogarray_like
The exogeneous data at which the derivative is computed, number of rows must be a multiple of ncut.
- lin_predarray_like
The values of the linear predictor, length must be multiple of ncut.
- Returns:
The
derivative
of
the
expected
endog
with
respect
to
the
- parameters.
