This method produces forecasts that are weighted averages of past observations where the weights of older observations exponentially decrease. Forms of exponential smoothing extend the analysis to model data with trends and seasonal components.

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 series anticipation when the data, in particular, doesn’t support any of the following; Trend: A slope either inclined upward or downward. WebSimple Exponential Smoothing is a forecasting model that extends the basic moving average by adding weights to previous lags. As the lags grow, the weight, alpha, is decreased which leads to closer lags having more …
WebExponential smoothings methods are appropriate for non-stationary data (ie data with a trend and seasonal data). ARIMA models should be used on stationary data only. One … WebApr 21, 2024 · SARIMA (Seasonal ARIMA) is a classical, statistical forecasting method that predicts the forecast values based on past values, i.e lagged values (AR) and lagged errors (MA). Unlike Holt-Winter's (or ETS), it needs the time series to be stationary before it can be used. That's where the "Integrated" part comes from.
