1 Introduction Partial Least Squares (PLS) is a widely used technique in chemometrics, especially in the case where the number of independent variables is signi cantly larger than the number of data points. There are many articles on PLS [HTF01, GK86] but the mathematical details of PLS do not always come out clearly in these treatments.

INTRODUCTION . Multicollinearity is often described as the statistical phenomenon wherein there exists a perfect or exact relationship between predictor variables. From a conventional standpoint, this occurs in regression when several predictors are highly correlated. Another way to think of collinearity is “co-dependence” of variables.
