[FRIAM] TETRAD

[Frank Wimberly]

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.
