Interaction Plot

Hi everyone,

I'd like to get help with generating a similar plot as below. The data has the continuous variable COST and two categorical variables A and B. I wanted to compare COST of different groups of A and B through the visualization.

Anyone has a suggestion about where to start? PROC ANOVA, PROC SGPLOT or PLOT GLM?

Thanks a lot!

I would use PROC GLM. Something like the following should get you started.

data A;
call streaminit(123);
do A = 1 to 3;
   s = 10*(A-2)**2;
   mean = 70 + 3*(A-2)**2;
   do B = 1 to 4;
      do i = 1 to 10;
         COST = B + rand("Normal", mean, s);
         output;
      end;
   end;
end;
run;

ods graphics on;
proc glm data=A;
class A B;
model COST = A | B;
run;
