A SAS event is used
to model any incident that disrupts the normal flow of the process
that generated the time series. Examples of commonly used events include
natural disasters, retail promotions, strikes, advertising campaigns,
policy changes, and data recording errors. You can create your own
set of events, or you can use events that are predefined by SAS.
The events that are
defined in the
event-data-set list
appear in the
Events Repository in SAS Forecast
Studio. In SAS High-Performance Forecasting, you can use an event
data set as a value for the INEVENT= option in the HPFDIAGNOSE and
HPFENGINE procedures. In
SAS/ETS, an event data set can be used by
the INEVENT= option in the X12 procedure.
When you set the EVENTDS=
option, all values that were specified by a previous EVENTDS= option
are replaced. A new specification of the option is not appended to
the value of the existing value. You can use this option to override
the default events or to add or delete event data sets.
To create event data
sets, see the HPFEVENTS procedure in the
SAS High-Performance
Forecasting User’s Guide.
