The VARMAX Procedure

Example 36.4 Illustration of ODS Graphics

This example illustrates the use of ODS Graphics. 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 36.4.1 through Output 36.4.3. These are a selection of the plots created by the VARMAX procedure.
