B. Falissard, Focused principal component analysis: Looking at a correlation matrix witha particular interest in a given variable, J COMPU G S, 8(4), 1999, pp. 906-912
This article proposes a simple graphical display that is similar to princip
al component displays in that approximations to correlation structures are
visualized. The proposed method differs from principal components in its fo
cus on a particular variable and the exact representation of the correlatio
ns between this variable and all others. The method is therefore applicable
to predictor-response data.
