Content-Type: text/plain; charset=US-ASCII

Hi and Happy Holidays to all

I've been asked to calculate the "biological variation" of a drug.  I
have 4 different tests measuring drug levels in 12 patients, with  each
test repeated on 4 different days in each patients.
 Can anyone refer me to an example I can follow to get this
accomplished?
Thanks for any help.

Jeff
