Comparaison de tendance centrale par l'analyse des transferts
The differences in the central tendency of two distributions on a finite set is represented by a series of transfers between modalities.

| Résumé: | The differences in the central tendency of two distributions on a finite set is represented by a series of transfers between modalities. A common model is presented which allows one to analyze these transfers for nominal, ordinal or metric variables, as well as for numerical ones. In particular, we define an index of difference between the distributions which boils down to Gini's distortion index in the case of a nominal variable and to the difference between the means in the case of a numerical variable. |
