WebAug 16, 2024 · Mean Absolute Percentage Error (MAPE) is the mean of all absolute percentage errors between the predicted and actual values. It is a popular metric to use as it returns the error as a percentage, making it both easy for end users to understand and simple to compare model accuracy across use cases and datasets. Formula for MAPE
Webmean absolute percent error (MAPE) as a numeric vector. The default choice is that any NA values will be kept ( na.rm = FALSE ). This can be changed by specifying na.rm = TRUE, such as mape (pre, obs, na.rm = TRUE) . References bullguard antivirus for gamersWebAug 28, 2024 · Absolute error, also known as L1 loss, is a row-level error calculation where the non-negative difference between the prediction and the actual is calculated.
