Dear R-users,
I'm wondering how to obtain Wilks-lambda values when discriminant
analyses have only one discriminant function (i.e. 2 categories to
discriminate between).
The use of manova(predictions~groups, test="Wilks") asks for multiple
response and the use of anova(lm(predictions~groups), test="Wilks")
simply does not consider the last term.
(The alternative question is whether such Wilks-lambda value is relevant
for those simple comparisons between two groups of predicted values or
whether t-test like are enough?)
Thanks a lot,
Joël
