Exponential smoothing explained
WebSingle exponential smoothing smoothes the data when no trend or seasonal components are present. The equation for this method is: Y ^ t = α ( Y t + ∑ i = 1 r ( 1 − α) i Y t − i), where Y ^ t is the forecasted value of the series at time t and α is the smoothing constant. Note that r < t, but r does not have to equal t − 1 . Web3 Types of Exponential Smoothing . Broadly, there are three types of exponential smoothing techniques that rely on trends and seasonality. They are; Simple Exponential Smoothing (SES) SES is used for time …
