"WebbThe exponential smoothing forecasting equation is x ^ t + 1 = 1.3877 x t − 0.3877 x ^ t At time 100, the observed value of the series is x100 = 0.86601. The predicted value for the series at that time is x ^ 100 = 0.856789 Thus the forecast for time 101 is x ^ 101 = 1.3877 x 100 − 0.3877 x ^ 100 = 1.3877 ( 0.86601) − 0.3877 ( 0.856789) = 0.8696 " - Simple exponential smoothing prediction model
