Predictor uses one of four forecasting techniques for time-series forecasting: Standard, Simple lead, Weighted lead, and Holdout. By default, Predictor uses Standard forecasting to select the best method.
To change which forecasting technique Predictor uses:
On the Options panel, select the forecasting technique to use for time-series:
Standard forecasting—Error measure between the fit values and the historical data for the same period; the default
Simple lead—Error measure between the historical data and the fit offset by a specified number of periods (lead)
Weighted lead—Average error measure between the historical data and the fit offset by 0, 1, 2, etc. periods, up to the specified number of periods (weighted lead)
Holdout—Error measure between a set of excluded data and the forecasting values. Predictor does not use the excluded data to calculate the forecasting parameters
For more information about each technique, see the Predictor sections of the Oracle Crystal Ball Reference and Examples Guide.
If you select Simple lead, Weighted lead, or Holdout, enter the appropriate lead or holdout in the box.
If all settings in the Predictor wizard are complete, click Run to run the forecast and produce results.
