Improvements have been introduced, a new component is added.
HAC. Hierarchical agglomerative clustering. Computing time has been dramatically improved. We will detail the new procedure used in a new tutorial soon.
CATVARHAC. Classification of the levels of the nominal variables. The calculations are based on the work of Abdallah and Saporta (1998). The component performs an agglomerative hierarchical clustering of the levels of qualitative variables. The Dice's index is used as the distance measures. Several kind of linkage criteria are proposed: single linkage, complete linkage, average linkage, Ward's method. A tutorial will come to describe the method soon.
