Here is an example of how do simulate data for a simple bivariate linear
model using SAS. I use this macro to generate a different random sample for
each student in the class, with data posted on the web for them and with
solutions to me. If you want a less hands-on approach, I recommend Drake
Bradley's DATASIM software.
TITLE1 'Simulation from Wuensch, Castellow, & Moore, JSB&P, 1991.'; %MACRO
MREG; DATA SOL; drop subject;
DO subject = 1 TO 100;
serious=round(5.5+1.6*NORMAL(0));
if serious > 9 then serious = 9;if serious < 1 then serious = 1;
sentence = round(-.92+1.16*serious+2.78*NORMAL(0));
if sentence < 1 then sentence = 1;if sentence > 15 then sentence = 15;
OUTPUT;FILE "C:\SimData\%name.dat";PUT sentence serious; end;

PROC REG simple corr; MODEL sentence = serious;
%MEND MREG;
