Grey prediction models play a significant role in forecasting energy demand, particularly the gm(1,1) model. To increase the prediction accuracy of the original gm(1,1) model, the corresponding residual gm(1,1) model is often recommended. However, the original and residual models that form the basis of the remnant grey prediction model are usually set up independently.
