Abstract : Inside the Statistical Implicative Analysis frame, implicative rules may be extracted while pondered by a measure called Intensity of Implication. The set of the non-symmetrical relationships that associate the different variables may be represented by a graph so called implicative. Inside the graph, relationships upstream and downstream from a central variable parted on either sides of this node can be sometimes noticed. This situation of a confluent is metaphorically said a two clusters implicative cone. On condition that the set is rather homogeneous and linked, giving conceptual meaning to this cone allows some kind of causalities/consequences isolation of it from the whole set. In this communication, we define criteria for the homogeneity of a cone and conditions for existence of causal relationships. Some significant examples illustrate our theoretical discourse.
