Abstract
Principal Component Analysis is mainly based on the covariance matrix or on the matrix of correlations. In this paper the approach is extended by deriving the principal components from the matrix of partial correlations. It is shown that appropriate interpretation of the results obtained by this approach can make it possible to overcome the difficulty of understanding the correlation structure of the variables in a set of variables after eliminating the effect of the variables in another set.
