Introduction
In our previous column1 we introduced CVA, one of the very early applications of multivariate analysis (1930s). In this column we will discuss SIMCA (officially it is Soft Independent Modelling of Class Analogies, but no one uses the long form!). SIMCA was invented 30 years later2 by another pioneer, Svante Wold (the man who coined the word “chemometrics”).
