Example 30.4 Illustration of ODS Graphics

This example illustrates the use of ODS Graphics. The graphical displays are requested by specifying the ODS GRAPHICS ON statement. For information about the graphics available in the VARMAX procedure, see the section ODS Graphics.

The following statements use the SASHELP.WORKERS data set to study the time series of electrical workers and its interaction with the series of masonry workers. The series and predict plots, the residual plot, and the forecast plot are created in Output 30.4.1 through Output 30.4.3. These are a selection of the plots created by the VARMAX procedure.
