The method puts more weight on the most recent sales data than on older data.

Webb1 apr. 2006 · The exponential smoothing methods are relatively simple but robust approaches to forecasting. They are widely used in business for forecasting demand for inventories (Gardner, 1985). They have also performed surprisingly well in forecasting competitions against more sophisticated approaches (Makridakis et al., 1982, … WebbExponential smoothing is useful when one needs to model a value by simply taking into account past observations. It is called "exponential" because the weight of past observations decreases exponentially. This method it is not very satisfactory in terms of prediction, as the predictions are constant after n+1.

WebbThe exponential smoothing forecasting equation is x ^ t + 1 = 1.3877 x t − 0.3877 x ^ t At time 100, the observed value of the series is x100 = 0.86601. The predicted value for the series at that time is x ^ 100 = 0.856789 Thus the forecast for time 101 is x ^ 101 = 1.3877 x 100 − 0.3877 x ^ 100 = 1.3877 ( 0.86601) − 0.3877 ( 0.856789) = 0.8696 smallcasehqWebbExponential Smoothing.
