The precision of Electrical power use calculations is often evaluated using normalized variations of Equations (one) and (two): normalized suggest bias error (nMBE) and coefficient of variation in root indicate squared mistake (cvRMSE). The two the MBE and RMSE are normalized using the imply with the calculated values. The nMBE indicates the general bias from the model but is matter to cancelation mistakes since it requires into account the sign of the standard error vector and should not be employed alone.
