Proc template Regression Plot with No intercept

Leo9 — Mon, 12 Mar 2018 16:50:22 GMT

Is there any option in proc template to plot regression plot with no intercept ?

regressionplot x = test1 y = test2 / name="fitline" legendlabel="Regression line";

No. You can run PROC REG and output the predicted values and then plot them using a series plot.

Haven't done regression line without using regression plot. Which parameters/predicated values from proc reg should be use to plot this ?

Here is an example with SGPLOT. The NOINT option forces the line through 0,0. The output statement stores the predicted values in the variable p.

proc reg data=sashelp.class;
   model weight = height / noint;
   output out=p p=p;
quit;

proc sort data=p; by height; run;

proc sgplot data=p;
   scatter y=weight x=height;
   series y=p x=height;
run;
