The events feature of Predictor enables users to define events, identifiable occurrences that have affected historical data and could affect predicted data. Users can define events for historical and predicted data.
When forecasting from historical data that includes a defined event, the effects of the event are removed from the data and then the forecasting methods are fit to the adjusted data. If there are repeating occurrences of events in the forecasted period, the effects of the events are applied to the forecasts obtained.
Notice that the adjusted data does not appear in the charts. Predictor shows the original data and the fits are adjusted visually to reflect the effects of the events. Any manual adjustments to the forecasts are performed after the effects of the events are applied to them.
For more information about events, see the Oracle Crystal Ball Predictor User's Guide.
