The accuracy of Electricity usage calculations is typically evaluated utilizing normalized variations of Equations (one) and (two): normalized signify bias error (nMBE) and coefficient of variation in root indicate squared mistake (cvRMSE). The two the MBE and RMSE are normalized using the necessarily mean with the measured values. The nMBE suggests the general bias on the product but is subject matter to cancelation glitches because it takes under consideration the signal of the standard mistake vector and really should not be employed on your own.
