- Abstract
- Several approaches to the decomposition of multivariate data arrays in terms of latent structure are developed within a common mathematical frame. The methods considered are (i) decomposition into principal components, also called singular-value decomposition, (ii) decomposition using the partial-least-squares approach and (iii) projection on to axes defined by selected variables or objects, so-called markers. Graphic display, being of major importance in interactive data exploration and classification, is discussed.
