Comparaison de tendance centrale par l'analyse de transferts
Mathématiques et Sciences humaines, Volume 134 (1996), p. 63-76

Comparison of central tendencies by means of transfer analysis.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.

La différence de tendance centrale entre deux distributions sur un ensemble fini est représentée par une série de transferts entre les modalités. Un modèle unique est proposé qui permet d'analyser ces différences pour des variables nominales, ordinales ou métriques aussi bien que pour les variables numériques. En particulier on définit un indice de différence entre les distributions qui se ramène à l'indice de distorsion de Gini dans le cas d'une variable nominale et à la différence entre les moyennes dans le cas d'une variable numérique.
