SAS FAQ #16: SAS/GRAPH scatter plots of predicted values

Question:

How do I output predicted values from PROC REG and display them in SAS/GRAPH's PROC GPLOT?

Answer:

Following the model statement in PROC REG, use an OUTPUT statement with the keyletter P to write the predicted values to a new dataset. This dataset can be subsequently used in PROC GPLOT. For example:

PROC REG ;
    MODEL y=x ;
   OUTPUT OUT=regout P=yhat ;

PROC GPLOT DATA=regout ;
   PLOT yhat*x ;
RUN ;

PROC GPLOT will produce a scatter plot utilizing the default SAS/GRAPH symbol settings. The predicted values YHAT will be plotted against the X values.
