Example 13.5 Illustration of ODS Graphics

This example illustrates the use of ODS graphics in the ESM procedure and uses the SASHELP.AIR data set to forecast the time series of international airline travel.

The graphical displays are requested by specifying the ods graphics on statement and the PLOTS= option in the PROC ESM statement. In this case, all plots are requested. Output 13.5.1 through Output 13.5.4 show a selection of the plots created.

For information about the graphics available in the ESM procedure, see the section ODS Graphics.

proc esm data=sashelp.air out=_null_
         lead=20
         back=20
         print=all
         plots=all;
   id date interval=month;
   forecast air / model=addwinters transform=log;
run;

Output 13.5.1 Smoothed Trend Plot

Output 13.5.2 Prediction Error Plot

Output 13.5.3 Prediction Error Standardized ACF Plot

Output 13.5.4 Forecast Plot
