missing value

hi,

I am using time series algorithm.and my prediction query is like this

SELECT PredictTimeSeries([Performance]) FROM [Stud_Model]

The output is like this

Date Perf

9/11/2006 90

10/11/2006 92

11/11/2006 93

12/11/2006 -- (no prediction)

1/11/2007 --(no prediction)

I dnt know why there is no prediction after certail date?

Thanks,

Karthik

The time series algorithm is based on regression trees which can become unstable as you move away from the time horizon, since you have predictions based on predictions. The algorithm tries to detect when this instability occurs and stops predicting at that point.

In future releases, we will have more user control over prediction stability and the behavior of the algorithm around this stability.
