Wouldn't readers be better off if the author wrote about this problem with PCA in the book, instead of ignoring it entirely?

- christopheraden 13y agoWhile I agree with you, if the author believed the entire method is invalid in all situations, he could make a strong argument that it wasn't worth the space to put it in at all. It would be a long book if it was filled with all the methods currently in production that did _not_ work!
