....left big cluster is linked to the low values of the sixth and the high values of the fourth variable. With a principal component analysis or a multidimensional scaling we can not detect the three clusters. At least one cluster analysis method (weighted clustering, adaptive k means clustering, see Mucha (1995)) is able to find the three clusters, but standard techniques like the (unweighted) Ward method fail to find them too. 6 Multivariate Exploratory Projection Pursuit A new set of indices will be proposed here. Univariate indices mainly find univariate structures and the bivariate indices both ....
