[R] discriminant analysis: prerequisites

[Christoph Lehmann]

Dear R users
Could someone explain me, why I need more observations than variables to
conduct a discriminant analysis (as I was told by one of our teachers)?

I have n = 66 observations, and 133 + 3 + 7 + 8 variables. Well, for the
first 133 variables, I could conduct a PCA first, to reduce the amount
of information.

Thanks for an answer.

Cheers

Christoph
