[FRIAM] TETRAD

[Frank Wimberly]

That tutorial is mostly a user's manual for the software.

A better explanation is on pp. 19 and following in

https://www.researchgate.net/publication/242448131_Causation_Prediction_and_Search

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.
