I have regression model of the form Y = X + X^2. I need to plot the observed and the predicted values of Y against X on the same plot. I am thinking of using the overlay option in PROC REG.
OUTPUT P gives the predicted values as far as I understood. But how do I save it in a variable, say Yhat?
How do I get the predicted values from the regression summary to write the statement plot Y*X Yhat*X/overlay ;
Thank You.
In PROC REG, in the PLOT statement, you get the predicted values via
plot y*x predicted.*x/overlay;
In PROC REG, in the PLOT statement, you get the predicted values via
plot y*x predicted.*x/overlay;
You can get more control over the graph appearance with proc sgplot. For example:
proc sgplot data=sashelp.heart noautolegend;
reg x=ageAtStart y=cholesterol / degree=2 cli
markerattrs=(symbol=circlefilled size=4) transparency=0.2;
run;
