Mean error rate percentage
WebSep 26, 2024 · The mean absolute percentage error (MAPE) is the percentage equivalent of MAE. The equation looks just like that of MAE, but with adjustments to convert everything into percentages. Just as MAE is the average magnitude of error produced by your model, the MAPE is how far the model’s predictions are off from their corresponding outputs on … In statistics, the mean percentage error (MPE) is the computed average of percentage errors by which forecasts of a model differ from actual values of the quantity being forecast. The formula for the mean percentage error is: where at is the actual value of the quantity being forecast, ft is the forecast, and n is the number of different times for which the variable is forecast.
