The SYSLIN Procedure

This example illustrates the use of ODS graphics. This is a continuation of the section Klein’s Model I Estimated with LIML and 3SLS. These graphical displays are requested by specifying the ODS GRAPHICS statement before running PROC SYSLIN. For information about the graphics available in the SYSLIN procedure, see the section ODS Graphics.

The following statements show how to generate ODS graphics plots with the SYSLIN procedure. The plots of residuals for each one of the equations in the model are displayed in Output 36.3.1 through Output 36.3.3.
