WebOct 21, 2024 · The mean absolute percentage error (MAPE) is one of the most popular used error metrics in time series forecasting. It is calculated by taking the average (mean) of the absolute difference between actuals and predicted values divided by the actuals. Please note, some MAPE formulas do not multiply the result (s) with 100. 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 … hilton hotels official site/reservations https://joxleydb.com
