Does anyone have a good (and specific) reference for an explanation for
the calculation of degrees of freedom in treatment contrasts? I checked
the indexes of Venables and Ripley 2002, Crawley 2002, and Neter et al.
(Applied Linear Statistical Models, 4th ed.), as well as the lm code. I
would happily accept a "verbal" email explanation as well.
Many thanks,
Hank Stevens
