Is it necessary to approximately balance the sample
size in the groups of the validation or holdout sample to
develop a good discriminant function? I am a little unclear
about the extent to which the prior probabilities can be
used to adjust for sample proportions which do not represent
the population proportions. I suspect there is a difference
between predictive and descriptive discriminant analysis in
regard to this question, btw. But I cannot find a textbook
that addresses this question.
Thank you.
