""""
SMAPE (Symmetric Mean Absolute Percentage Error) is a popular accuracy metric used in forecasting to measure the relative difference between the predicted and actual values. It is particularly useful when the values being forecasted have different scales or magnitudes.
The purpose of SMAPE is to provide a way to measure the accuracy of a forecasting model that takes into account both the magnitude and direction of the errors. Unlike other accuracy metrics such as MAE (Mean Absolute Error) and RMSE (Root Mean Squared Error), SMAPE is symmetric and gives equal weight to over- and under-estimations of the actual value.
SMAPE is calculated as the average absolute percentage difference between the actual and predicted values, expressed as a percentage of the sum of the actual and predicted values. The formula for SMAPE is:
SMAPE = (100 / n) * Σ(|F_t - A_t| / (|F_t| + |A_t|))
