Apr 23, 2012 at 15:23 comment added R Hahn It is worth mentioning that in this context a "causal diagram" and a "graphical model", while both represented by directed graphs, are different things in terms of their interpretation. In particular, graphical models encode conditional independence relationship among random variables and a big part of Pearl's work is devoted to driving home the point that these relationships are not in themselves sufficient to tell causal stories.
