Traceable Regressions

Dans cet article, nous définitions et étudions le concept de traçabilité des régressions et l'appliquer á quelques exemples. Régressions traçables sont des séquences de distributions conditionnelles dans les réponses individuelles ou conjointes pour lesquelles un graphe correspondant capte non seulement une structure indépendance, mais représente, en outre, dépendances conditionnelles qui permettent le traçage des voies de la dépendance. Nous donnons les propriétés nécessaires pour transformer ces graphes et des critères graphiques de décider si un chemin dans le graphe induit une dépendance. Les contraintes beaucoup plus fortes sur les distributions qui sont fidèles á un graphe sont comparés á ceux nécessaires pour les régressions traçables.
