Fig. 2: The evaluation of explanatory power for each WU, EU and EC feature.
From: Enhancing the explanation of household water consumption through the water-energy nexus concept
a. Explanatory power estimated based on R2. The numbers indicate the decrease in R2 when removing a WU, EU or EC feature from the model with replacement. b Explanatory power estimated based on RMSE. The numbers indicate the increase in RMSE for each removal case. c Explanatory power estimated based on MAPE. The numbers indicate the increase in MAPE for each removal case. The results were estimated by deploying the XGBoost technique. The learning rate was constant in each case.
