*4.1. Comparison of CPM with Real Value*

The simulation results are shown in Figure 12. The prediction of the CPM coincides with the real value *v*. The prediction data are shown in Table 3. Comparing the real value *v* with the CPM, the predicted absolute error is *e*1. Selecting three days (123, 124, and 125) for calculation gives the CPM prediction with the MRE (Δ<sup>1</sup> = *<sup>e</sup>*<sup>1</sup> *<sup>v</sup>* × 100%) of 2.4%, 3.3%, and 5%, respectively. Therefore, the MRE (Δ1) of the prediction by the CPM is not more than 5%.
