Subject:      ranuni - simulation data help
Content-Type: text/plain; charset="iso-8859-1"

Please help.  I am new to SAS, and I am trying to generate 300 observations with specific proportions based on education level.

I would like for education level to equal 1:  40% of the time, 2:  20% of the time, 3:  10% of the time, 4:  5% of the time an 5:  25% of the time.  My code is below, but it is giving me the following, please advise where I am going wrong....

I am getting the following  for education level               1: 41.33     2: 16.67     3:  9.67    4: 7.33    5: 25


data k1; drop num;

do id = 1 to 300;

num = ranuni(0);

if num lt .4 then educ_lev = 1;

else if num ge .4 & num lt .6 then educ_lev = 2;

else if num ge .6 & num lt .7 then educ_lev = 3;

else if num ge .7 & num lt .75 then educ_lev = 4;

else educ_lev = 5;

output;

end;



Thanks
