WebApr 15, 2024 · Using an independent dataset to evaluate the estimation accuracy of the developed algorithm, the results show that the estimation performance of this algorithm is significantly improved compared to the two other algorithms used; the mean absolute percentage errors (MAPE) decreased from 72.56% and 52.21% to 32.61%, and the root … WebJun 15, 2024 · It depends where you apply division to make error relative! Mathematically, when you divide the difference between the predicted output and actual (expected) output T i − X i by T i then error will be considered Relatively which means that each residual is scaled against actual value or normalized by that .
