TETRAD
Locked

Joe Ramsey took over my work on the TETRAD project in the Philosophy Department at Carnegie Mellon when I left. It's a major project to develop software for doing statistical causal reasoning. Sometimes correlation is causation.
Joe just posted this in Facebook: I didn't know if it was OK to say yet, but word is getting out, so I guess it's OK. A project I've been working on for the last 20 years in the Philosophy Department at Carnegie Mellon, TETRAD, was just selected as one of four winners of the prestigious SAIL award. It's a great honor. Ours was a "leading" award. There were 800 projects that applied for consideration. EDIT: This has been a long-running project, started by Clark Glymour, Peter Spirtes and Richard Scheines some 10 years before I started on it. We've had considerable help along the way as well. So it's definitely been a group effort! --- Frank C. Wimberly 140 Calle Ojo Feliz, Santa Fe, NM 87505 505 670-9918 Santa Fe, NM - .... . -..-. . -. -.. -..-. .. ... -..-. .... . .-. .

Frank,
Would you say more about the work? What sort of framework is used to speak about the relation between correlation and causation? -- Sent from: http://friam.471366.n2.nabble.com/ - .... . -..-. . -. -.. -..-. .. ... -..-. .... . .-. .

Thanks, Jon. I gave a Friam Colloquium at SFI on the topic back in the day. Unless you have background knowledge, which you usually do, you can't decide which of two correlated variables causes the other. But if you have a set of variables as you usually do in social science and medicine you can use the Causal Markov Condition and the concept of Faithfulness to infer an equivalence class of causal digraphs which will frequently share a set of causal edges. I will look for a good tutorial on the subject and mail a link to Friam. --- Frank C.

Here is a TETRAD tutorial. See the Calvin and Hobbes cartoon. https://rawgit.com/cmu-phil/tetrad/development/tetrad-gui/src/main/resources/resources/javahelp/manual/tetrad_tutorial.html --- Frank C.

That tutorial is mostly a user's manual for the software. A better explanation is on pp. 19 and following in Sorry, Glen, it's a book but you only need a few pages to see how correlation (in the form of conditional independence) is causation.
