Raphael Fraser:
Thank you Joseph. I was trying to reproduce the results in Garrett
Fitzmaurice book, Applied Longitudinal Analysis p.116-7 Tables 5.3-5.5
It's the same dataset (lead concentrations in blood of children treated with a
chelating agent) and SAS code, so the do-file that I posted should reproduce
the results in _Applied Longitudinal Analysis_ exactly. I don't have the
book, so let me know if it doesn't.
