Exponential smoothing c#
WebJun 5, 2001 · Description: Exponential smoothing is defined as: Y2 (1) = Y (1) Y2 (I) = ALPHA*Y (I) + (1-ALPHA)*Y2 (I-1), I > 1. where Y is the original series and Y2 is the smoothed series. That is, the current smoothed value is a weighted average of the current point and the previous smoothed point. ALPHA is the smoothing parameter that defines … WebMar 1, 2024 · By Jim Frost 5 Comments. Exponential smoothing is a forecasting method for univariate time series data.
