I'm trying to find a dataset with examples of data matrices and their principal components.
I know that I could construct my own dataset using standard implementations found in python, or octave libs, but I want to find a dataset done for other people and maybe already used on other works because I want make sure people will not think that I generated some data that "helps" my implementation.
Searching on the internet, I have found some datasets like this one, but they don't have the principal components calculated.
So, does anyone here know such dataset?
