Causal Analysis in Theory and Practice

Antonio Forcina writes:

I have tried to read Judea and Ilya's paper on effect of treatment on the treated which sound much more general than anything else I have read on the subject before. Unfortunately I was unable to follow their proof and could not find an instance where the ETT effect is identifiable. The only instance where I new that ETT was identifiable is with an instrumental variable under certain restrictions, instead I imagine that identifiability here means without restrictions other than those encoded in the DAG.The most clear treatment of the subject I new until now is in a paper by Hernan and Robins in Epidemiology 2006; and I do not understand why the discussion on Forcina's paper by Robins, Vander Weele and RIchardson is so popular.

The following material is given to people who will attend my tutorial at the JSA meeting August 5 2009, But it might also be of interest to other students of causality. The survey article: "Causal inference in statistics: An Overview" is a recent submission to Statistics Survey which condences everything I know about causality in only 40 pages.
