Abstract

Selected methods from uni‐ and multivariate analysis of correlation are discussed and applied to a 3‐dimensional data array of the object‐variable occasion type. The data resulted from trace element determinations (by x‐ray fluorescence analysis) in human tissues. Special attention is devoted to 3‐way principal component analysis, partial least squares, linear characteristics and the nonparametric rank correlation coefficient by Kendall. It is shown that the correlations between interior human tissues (brain, liver, kidney) are strongly governed by a specific set of toxic trace elements (As, Se, Hg, Pb, Ni). However the relations between tissues and hair, which are of special interest in medicine, turn out to be rather weak. This results in an unsatisfactory prediction of toxic elements in tissues by those in hair.
