WebMar 26, 2024 · Symmetric mean absolute percentage error (SMAPE) (8) SMAPE = 100% m m ∑ i = 1 Xi − Yi ( Xi + Yi) / 2 (best value = 0; worst value = 2) Initially defined by Armstrong (1985), and then refined in its current version by Flores (1986) and Makridakis (1993), SMAPE was proposed to amend the drawbacks of the MAPE metric.

WebSep 9, 2024 · Unlike the MAPE, which divides the absolute errors by the absolute actual values, the SMAPE divides by the mean of the absolute actual AND the absolute predicted values. This counters MAPE’s deficiency for when the actual values can be 0 or near 0. I will not be spending too much time in this metric as it is rarely selected. WebThe symmetric mean absolute percentage error (SMAPE) is utilized to measure the anticipated accuracy of models. It is computed as: SMAPE = (1/n) * Σ ( measure – certain / ( ( certain + measure )/2) * 100 where: Σ – a symbol which means “sum” n – sample size actual – the specific data value forecast – the anticipated data amount
