What Is Mean Absolute Percentage Error

What Is Mean Absolute Percentage Error - MAPE (Mean Absolute Percentage Error) is a common regression machine learning metric, but it can be confusing to know what a good score actually is. In this post, I explain what MAPE is, what a good score is, and answer some common questions that people have. Stephen Allwright 15 Aug 2022 What Is Mean Absolute Percentage Error One of the most common metrics of model prediction accuracy mean absolute percentage error MAPE is the percentage equivalent of mean absolute error MAE Mean absolute percentage error measures the average magnitude of error produced by a model or how far off predictions are on average

What Is Mean Absolute Percentage Error

One of the most common metrics used to measure the forecasting accuracy of a model is the mean absolute percentage error, often abbreviated as MAPE. It is calculated as: MAPE = (1/n) * Σ (|actual - forecast| / |actual|) * 100 where: Σ - A symbol that means "sum" n - Sample size actual - The actual data value forecast - The forecasted data value Mean absolute percentage error (MAPE) is a metric that defines the accuracy of a forecasting method. It represents the average of the absolute percentage errors of each entry in a dataset to calculate how accurate the forecasted quantities were in comparison with the actual quantities.
