Exponential smoothing including Trend (also known as Forecast Including Trend (FIT)) Assume an initial starting F1 of 20,000 units, a trend (T1) of 500 units, an alpha of 0.2, and a delta of 0.1. The forecast including trend for period 1 (FIT1) would be period 2 (F2) would be the T component for period 2 (T2) would be be which would be the final forecast for period 2. and the forecast including trend for period 2 (FIT2) would Now, assume that the actual for period 2 (A2) turned out to be 21,610 units, then the F component for period 3(F3) would be period 3 (T3) would be final forecast for period s. which would mean that the forecast including trend for period 3 (FIT3) would bi and the T component for , which would be the
