Thank you!!
 
But is this based on your professional judgement, educated guess or a literature I could refer to. I would like to learn this stuff myself.

Thank you very much for your e-mail and suggestions regarding fpower
and anove (you are absolutely right, thanks for that).

If I can ask, why would you run "simpower nm year, reps(2000)" using 2000?

Once again, many thanks
Aggie

Aggie-

The minimum I would recommend is 1000 reps but since you have 8 groups
I think 2000 would be better.

Best of luck.
