NominalGEE.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, number of rows must be a multiple of ncut.

lin_pred : array_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.
