 [A theory of inferred causation](http://ftp.cs.ucla.edu/pub/stat_ser/r156-reprint.pdf) - with Thomas S. Verma.
 > Introduces minimal-model semantics as a basis for causal discovery,
 > and shows that causal directionality can be inferred from patterns
 > of correlations without resorting to temporal information.

 [Causal diagrams for empirical research](http://ftp.cs.ucla.edu/pub/stat_ser/R218-B-L.pdf) - extended version linked.
 > Introduces the theory of causal diagrams and its associated do-calculus;
 > the first (and still the only) mathematical method to enable a
 > systematic removal of confounding bias in observations.
