Exponential smoothing spss
WebSep 25, 2024 · Exponential smoothing is a family of forecasting methods which computes a weighted average of past observations as the forecast. The weights are decaying exponentially as the observations get older. As a result, the more recent the observation, the higher its weight in the forecast. WebExponential smoothing methods are often used in time series forecasting. They utilize the exponential window function to smooth a time series. There are multiple variations of smoothing methods, too. The simplest form of exponential smoothing can be thought of this way: s0 = x0 st = αxt +(1 −α)st−1 = st−1 +α(xt −st−1) s0 = x0 st ...
