Pat: Maybe I'm being egotistical, but were you refering to me regarding stats? If you clue me into which posts to which you are referring, I'd be happy to put my stats professor hat on. However, I'm not sure if you are referring to K. Detwyller's post about infant mortality in developing nations or someone elses. : )Chris Hafner-Eaton, PhD, MPH, CHES, IBCLC email: [log in to unmask] : ) : )HSR & Health Educational Consultant voice/fax: 541 753 7340 : ) : )LLLLLLLLLLLLL**CHANGE THE WORLD, NURTURE A CHILD!**LLLLLLLLLLLLLLLLLL : )
