Double exponential smoothing filter
WebTt = γ [ Lt – Lt –1] + (1 – γ) Tt –1. = Lt –1 + Tt –1. If the first observation is numbered one, then level and trend estimates at time zero must be initialized in order to proceed. The initialization method used to determine how the smoothed values are obtained in one of two ways: with optimal weights or with specified weights.
