You probably need something from the level just below MEMSS. There's Maindonald & Braun, although I don't have a copy to hand just now. You might also take a look at the Faraway PDF (or buy his more recent book) at
http://cran.at.r-project.org/other-docs.html
Specifically, take a look chapter 15 and chapter 3.1--3.
(And apologies if I came across a bit abrasive, but you did ask the same question about four times...)
