Hello.  Please excuse this off-topic request, but I know that the
question has been debated in summary form on this list a number of
times.  I would find a paper that lays out the advantages and
disadvantages of using different types of SS in the context of
unbalanced data in  ANOVA, regression and ANCOVA, especially including
the use of different types of contrasts and the meaning of the
hypotheses that are tested in such cases.

Thanks for any leads.
