Sorry there were 2 typos in my note:
John Fox's posting provided a lot of information. Briefly, the "Types" refer to whether effects are adjusted for all other effects in the model (Types II, III, IV) or no (Type I or sequential tests only adjust for
no -> not
EARLIER terms in the model). See John's posting for definitions of Types II and III and for reasons to almost always use II or III.
II or III -> II over III Sorry about that Frank ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
