Show the exponential smoothing forecasts using α = 0.1, and α = 0.2. exponential smoothing week α = 0.1 α = 0.2 13 (b) applying the mse measure of forecast accuracy, would you prefer a smoothing constant of α = 0.1 or α = 0.2 for the gasoline sales time series? an smoothing constant provides the more accurate forecast, with an overall mse of . (c) are the results the same if you apply mae as the measure of accuracy? an smoothing constant provides the more accurate forecast, with an overall mae of . (d) what are the results if mape is used? an smoothing constant provides the more accurate forecast, with an overall mape of .
