seconds. The basis of the complex computations required is multivariate statistics, a branch of
chemometrics employing such mathematical and statistical techniques as multiple linear regression
(MLR) principal component analysis (PCA) and partial least squares (PLS) regression. However, a
description of these techniques is beyond the scope
