No need to dump your entire data set on us. Just a few representative
values will do.

What's PCA? What's princomp?

Have you tried it? What happens?

This is a list for people learning Python the programming language. We are not
experts on numpy, which is a specialist package for scientific use. We are not
statisticians either. You can probably assume that most of us know what
"standard deviation" is. Anything more complicated than that, you should ask
on a specialist numpy mailing list.

Good luck!
