Thank you Scott! Can I use a list of variables such as ul(tr1 tr2
tr3...), where tr1 is a binary variable indicating membership in
treatment group 1, tr2 a binary variable indicating membership in
treatment group 2, etc.? What I want to achieve is: if tr1 = 1 then use
ul(0), if tr2 = 1 then use ul(10) etc.
Your help is much appreciated,
Andrea
