Setting single exponential smoothing parameters

A single exponential smoothing is a type of weighted moving average where the weights decrease exponentially for each successive time period.

1. Open the Model page of the Forecast editor.
2. Click Add.
   The Forecast model selection page of the Add Model wizard opens.
3. Click Single exponential smoothing and then click Next.
   The Single exponential smoothing page of the Add Model wizard opens.
4. Specify a value in the Exponential smoothing constant field.
   The number must be between zero and one. High values give recent periods more weight and low values give more weight to past data.
5. Click Finish.
   The Add Model wizard closes and the forecast model is displayed in the table.
