Corrélation entre variables nominales, ordinales, métriques ou numériques
A correlation coefficient is defined for the empirical joint distribution of two statistical variables, whatever be the a priori structure, nominal, ordinal, métrical or numerical of each other. Obtaining a common formalism for all these structures allows us to refine the analysis of correlation in...

| Sumari: | A correlation coefficient is defined for the empirical joint distribution of two statistical variables, whatever be the a priori structure, nominal, ordinal, métrical or numerical of each other. Obtaining a common formalism for all these structures allows us to refine the analysis of correlation in terms of homogeneity (ordered variables) underlying order (non-ordered variables) or induced order (mixed case). |
