I am trying to do a four-factor repeated measures ANOVA with Mma.
neither one will give me Sums of Squares of Mean Squares for my main effects
and interactions. I have been (rather tediously) collecting data within
cells, doing the summing and squaring of Sums. Before I spend another several
hours on the analysis, I was wondering if anyone else has figured out how to
get Sums of Squares and Mean Squares from the Regress or Designed Regress
packages. I can compose my own F ratios.
As the design is a repeated-measures or within - subjects design, the
appropriate error terms are different from the between-subjects or one
measurement per experimental unit, so I really need the Sums of Squares for
each effect.
Alternatively, has anyone written a package that does this? I've looked
through mathsource but did not find anything....
