Setting multiplicative decomposition parameters

A multiplicative decomposition extracts trend, seasonality, and cyclicity information from the data and uses these elements to predict future values.

1. Open a forecast in the Model editor.
2. Click Add.
   The Forecast model selection page of the Add Model wizard opens.
3. Click Multiplicative decomposition and then click Next.
   The Multiplicative decomposition page of the Add Model wizard opens.
4. Specify the frequency at which you expect to see seasonal effects on the data in the Seasonal frequency drop-down list.
5. Specify the frequency at which you expect to see cyclical effects on the data in the Cycle length drop-down list.
6. Click Finish.
   The Add Model wizard closes and the forecast model is displayed in the table.
