PCA and PLS aims:to get some

insight into the bilinear factor models Principal Component Analysis

(PCA) and Partial Least Squares (PLS) regression, focusing on the

mathematics and numerical aspects rather than how s and why s of

data analysis practice. For the latter part it is assumed (but not

absolutely necessary) that the reader is already familiar with these

methods. It also assumes you have had some preliminary experience

with linear/matrix algebra.
