PROC SGPANEL REGRESSION DISPLAY-R SQUARE

[Cruise]

Hi SAS experts,

I'd like to display R-square or slope on the each individual poverty level specific panel in the plot below. I know that there is INSET function but I couldn't work it out. Any hints or suggestions highly appreciated?

Notice the last column I added .

The solution worked with the given demo data. However, do you know why it doesn't work when I add one more variables into the panel statement and extend my layout to lattice?

The error I get is:

3014 FORMAT POVER $POVER.;
3015 INSET R_Square / position=top;

Oops, I just noticed that you added a column with R-square. I thought R-square in INSET was built in. I think I got it. I have to calculate S-squares then use INSET.
