Well, it is (of course) totally unfair of me to expect you to control the
design, or - in this case - to explain what the heck your bosses are doing.
But I think it is important to point these aspects out. Your bosses may not
have given you enough direction here, and that's their fault. Go back and
make sure they know what you are coding up, and why.
It may be that they'll have some helpful suggestions for you. Or it may be
that we can work out a more effective approach to achieve your goals. I'm
still not clear on why you have coded your project the way that you have.
And please write back to SAS-L, instead of to me personally. Thanks.
