Another
important tool in chemometrics is Partial Least Squares regression for model
building between a multivariate descriptor and a uni- or multivariate response
block. PLS, like PCA, is a bilinear and model free method. Next to the
predictive performance, the (graphical) diagnostics for model interpretation are
explained. We will examine both the (essential) mathematics and the practical
issues of PLS modeling, using the example to illustrate choices and results.
