On association

D. Costantini & U. Garibaldi
In the present paper we face, from a general perspective, the problems posed by statistical inferences in the case of two modalities. The analysis of the association is performed both from the ipotetical-deductive point of view (tests of significance) and from the inductive one (predictive inferences). That analysis is performed with the view of the foundational aspects of statistical inferences not caring too mach about the mathematical subtleties.
