The absolute difference between At and Ft is divided by half the sum of absolute values of the actual value At and the forecast value Ft. The value of this calculation is summed for every fitte… Websymmetric Mean Absolute Percentage Error (sMAPE) Having discussed the MAPE, we also take a look at one of the suggested alternatives to it — the symmetric MAPE.
