I think the original paper is
@Article{flm:Wilkinson+Rogers:1973,
author = {G. N. Wilkinson and C. E Rogers},
title = {Symbolic Description of Factorial Models for
Analysis of Variance},
journal = {Applied Statistics},
year = 1973,
volume = 22,
pages = {392--399}
}
but I don't have a copy of the paper, so I don't know what's in there.
I put up a pdf copy from JSTOR at http://www.R-project.org/gR/papers/ Best, Z
best, fritz
