Hi Rafael,
What about multivariate logistic regression?

It seems that you have already groups defined.
Discriminant analysis would probably be more appropriate for what you want.
Best regards,
Rafael Duarte

hierarhical cluster analysis of groups of vectors
I want to do hierarchical cluster analysis to compare 10 groups of
vectors with five vectors in each group (i.e. I want to make a dendogram
showing the clustering of the different groups). I've looked into using
dist and hclust, but cannot see how to compare the different groups
instead of the individual vectors. I am thankful for any help.

Analysing ordinal/nominal data
Hi!
I'm looking for a solution to analyse data, which consists of
dichotomous responses (yes/no) for 2 multinomial ordinal variables. I
was trying glm() and got hierarhical models treating all variables as
nominal, but I can't figure out how to tell glm() to use a model for
ordinal data like this:
log(Mij) = intercept + X + Y + Z + beta*(x-x')*(y-y')
where beta is a regression factor for interaction between X and Y.
Do you know a trick to code it in R...

Probably, anything is possible, but you would have to write your own
tools
