Since there's likely some serious time and location dependence
here, I suggest you get a copy of Pinheiro and Bates.
@Book{PinheiroBates2000,
author = {Jos\'e C. Pinheiro and Douglas M. Bates},
title = "Mixed-Effects Models in S and S-PLUS",
publisher = {Springer-Verlag},
year = {2000},
address = {New York}
}
Since performing statistical consulting for free is a
dangerous prescedent to the profession, I'll leave it
at that :)
Cheers
Jason
