Data Set Selection Window
Use this resizable window to select a data set to process by specifying a library and a SAS data set or view. These selections can be made by typing, by selecting from lists, or by a combination of the two. In addition, you can control the time ID variable and time interval, and you can browse the data set.
Access this window by using the Browse button to the right of the Data Set field in the Time Series Forecasting, Automatic Model Fitting, and Produce Forecasts windows. It functions in the same way as the Series Selection window, except that it does not allow you to select or view a time series variable.
Controls and Fields
- Library
is a SAS libname assigned within the current SAS session. If you know the libname associated with the data set of interest, you can type it in this field. If it is a valid choice, it will appear in the libraries list and will be highlighted. The SAS Data Sets list will be populated with data sets associated with that libname. See also Libraries under Selection Lists.- Data Set

is the name of the ID variable for the selected input data set. To specify the ID variable, you can type the ID variable name in this field or select the control arrows to the right of the field.- Time ID Select button
opens the Time ID Variable Specification window.- Time ID Create button
opens a menu of methods for creating a time ID variable for the input data set. Use this feature if the data set does not already contain a valid time ID variable.- Interval
is the time interval between observations (data frequency) in the selected data set. If the interval is not automatically identified by the system, you can type in the interval name or select it from a list by clicking the combo box arrow. For more information about intervals, see Chapter 4, Date Intervals, Formats, and Functions, in this book.- OK
closes the Data Set Selection window and makes the selected data set the current input data set.- Cancel

opens a Viewtable window for browsing the selected data set.- Reset
resets the fields to their initial values upon entry to the window.- Refresh

Selection Lists
- Libraries

displays a list of currently assigned libnames. You can select a libname by clicking it with the left mouse button, which is equivalent to typing its name in the Library field.If you cannot locate the library or directory you are interested in, go to the SAS Explorer window, select "New" from the File menu, then select "Library" and "OK." This opens the New Library window. You also assign a libname by submitting a libname statement from the Editor window. Select the Refresh button to make the new libname available in the libraries list.
- SAS Data Sets
displays a list of the SAS data sets (data files or data views) contained in the selected library. You can select one of these by clicking with the left mouse button, which is equivalent to typing its name in the Data set field. You can double-click a data set name to select it and exit the window.
