Hello,
Is there a way inside Forecast Studio (or another method) to force Forecast Studio to overide the time series forecast for future months to a preset minimum or maximum value when it is out of the threshold only? I'd like to set thresholds so that the forecast will be more reasonable given our expectations.
Thanks!
Hi:
Note that using min/max adjustments will set a bound to the statistical forecasts. If your project is hierarchical your final forecasts may be different from the statical forecasts. If you need to set bounds on the final forecasts, I can't think of a direct way of doing it inside Forecast Studio.
However, there other ways to accomplish that. Each one requires a bit of coding, but not much. These three come to my mind. There may be other alternatives I can't think about right now.

Hello -
You may want to look into using "adjustment variables" - from SAS Forecast Studio 14.2 User's Guide (chapter 6):
"What Is an Adjustment Variable?
Systematic variations and deterministic components are included in time series data. By adjusting the time series for known systematic variations or deterministic components, the underlying stochastic (unknown) time series process can be more readily identified and modeled. For more information about adjustment variables, see the "Adjustment Step" topic in the SAS Forecast Server Procedures: User’s Guide."
Thanks,
Udo
