WebExponential smoothing is a time series forecasting method for univariate data. It can be extended to support data with a trend or seasonal component. It can be used as an alternative to the popular ARIMA family of models. Exponential smoothing of time series data assigns exponentially decreasing weights for newest to oldest observations. WebThe simplest of the exponentially smoothing methods is naturally called simple exponential smoothing (SES) 14. This method is suitable for forecasting data with no clear trend or seasonal pattern. For example, the data in Figure 8.1 do not display any clear trending behaviour or any seasonality. (There is a decline in the last few years, which ...
WebExponential smoothing is one of the oldest and most studied time series forecasting methods. It is most effective when the values of the time series follow a gradual trend and display seasonal behavior in which the values follow a repeated cyclical pattern over a given number of time steps.
