 Reichenbach’s Common Cause Principle is closely related to the Causal Markov Condition that is commonly employed in causal modeling. A version of the Causal Markov Condition was first proposed by Kiiveri, Speed, and Carlin (1984). Detailed programs in causal modeling featuring the Causal Markov Condition have been developed by Pearl (2009) and Spirtes, Glymour and Scheines (2000).
