A hierarchical clustering family based on the affinity coefficient and generated by a suitable extension of the Lance & Williams formula appears to be the support of inferential statistics methodology applied to frequency data set. In this paper we are dealing with contingency tables concerning the distribution of human immunodeficiency viruses (HIV) by regions and subject groups in Angola. Multivariate methods in the clustering family incorporate a subfamily of probabilistic models and inference approach refers to bi/tridimensional loglinear models.
