*4.3. Comparison of CPM with CM*

The simulation results are shown in Figure 14. Compared with the real value *v*, the prediction error of the CM is larger than in the CPM. The prediction data are shown in Table 3. Comparing the real value of *v* with the CM, the predicted absolute error is *e*3. Selecting three days (122, 123, and 125) for calculation gives the CM prediction with the MRE (Δ<sup>3</sup> = *<sup>e</sup>*<sup>3</sup> *<sup>v</sup>* × 100%) of 5.4%, 5.6%, and 7.2%, respectively, while the CPM prediction gives the MRE (Δ1) of 0.6%, 2.4%, and 5%, respectively. Therefore, the prediction result of the CPM when compared with the CM has the MRE reduced by 4.8%.
