Pour une détection robuste, distinguez bien les colonnes continues (test KS) des catégorielles (chi²). Ajoutez une vérification préalable de la présence des mêmes colonnes dans les deux jeux. Pour éviter les faux positifs avec un grand volume de données, envisagez un seuil de p-value plus strict (ex. 0.01) ou l'utilisation de la correction de Bonferroni.
