The question is what is the difference between a causal model and regression or classification (an associational model). And the main difference is that: While you can do regression from causes to their effect, or from effects to some hypothetical cause; in a causal model, the relationships are directed (causes to effects). These directions are required to support interventional reasoning, which associational models cannot support.
Jul 27, 2014 at 12:59 comment added generic_user Well, isn't associational basically the default? And wouldn't causal be nested within associational? I've never heard of anyone ever talk about an ''associational model'', except perhaps disparagingly in the case of one where the supposedly causal effects were confounded.
