This table contains the statistics for the selected model of each time seriesan aggregation of transactional data into specified time intervals and sorted according to unique combinations of the default attributes (BY variables). This table includes all of the BY variables assigned to the project, variables that identify the selected model, the region over which the fit statistics are computed, and variables for the statistics of fit. The statistics of fit can be used for model selection and are described in Descriptions of Model Selection Criteria. For more information, see the description of the OUTSTAT Object.
The statistics in this table are listed on the Data tab and in the Time Series Viewer and Forecast Viewer as Forecast attributes. You can use these attributes to create filtersa set of specified criteria that are applied to data in order to identify the subset of data for a subsequent operation, such as continued processing. in all of the viewers. See Creating Filters for more information.
There are two forecasta numerical prediction of a future value for a specified time period for each unique combination of BY variable values attributes that are not included in the OUTSTAT table but are computed separately. These are described below.

Flat Forecast |
_FLAT |
Indicates the presence of flat forecasts.
Forecasts for a time series are determined to be flat when the forecast range (maximum - minimum predicted value) is less than or equal to 0.00001. The _FLAT attribute differs from the flat forecasts in the Execution Summary for a modeling node. The _FLAT attribute includes all time series where the value could be positive, negative, or zero. |
|
Almost Flat Forecast |
_ALMOST_FLAT |
indicates the presence of almost flat forecasts, as defined on the Reporting tab in the Project Settings.
