Time Series Forecasting Window
The Time Series Forecasting window
is the main application window which appears when you invoke
the Time Series Forecasting System.
It allows you to specify a project file and an input
data set and provides access to the other windows
described in this chapter.
Controls and Fields
is the name of the SAS catalog entry in which forecasting models
and other results will be stored and from which
previously stored results are loaded into the forecasting system.
You can specify the project by typing a SAS catalog entry name
in this field or by selecting the Browse button to right of this field.
If you specify the name of an existing catalog entry,
the information in the project file is loaded.
If you specify a one level name, the catalog name is assumed to be
fmsproj and the library is assumed to be sasuser.
For example, samproj is equivalent to sasuser.fmsproj.samproj.
- Project Browse button
brings up the Forecasting Project File Selection window
to enable you to select and load the project from a list
of previously stored projects.
is a descriptive label for the forecasting project.
The description you type in this field will be stored
with the catalog entry shown in the Project field.
- Data Set
is the name of the current input data set.
To specify the input data set,
you can type the data set name in this field or use the Browse
button to the right of the field.
- Data set Browse button
brings up the Data Set Selection window
to enable you to select the input data set.
- Time ID
is the name of the ID variable for the input data set.
To specify the ID variable, you can type the ID variable name
in this field or use the Select button. If the time ID variable
is named date, time, or datetime, it is automatically
picked up by the system.
- Select button
brings up the Time ID Variable Specification window.
- Create button

is the time interval between observations
(data frequency) in the current input data set.
If the interval is not automatically filled in, you can type an
interval name or select one from the popup list.
For more information on intervals, see

to display plots of series in the current input data set.
- View Data as a Table
brings up a Viewtable window for browsing the selected input data set.
- Develop Models
brings up the Develop Models window
to enable you to fit forecasting models
to individual time series and choose the best models to use to produce
the final forecasts of each series.
- Fit Models Automatically
brings up the Automatic Model Fitting window
for applying the automatic model selection process
to all series or to selected series in an input data set.
- Produce Forecast
brings up the Produce Forecasts window
for producing forecasts for the series in the current input data set
