Class MeekRules

java.lang.Object

edu.cmu.tetrad.search.MeekRules

All Implemented Interfaces:

ImpliedOrientation

public class MeekRules
extends Object
implements ImpliedOrientation

Implements Meek's complete orientation rule set for PC (Chris Meek (1995), "Causal inference and causal explanation with background knowledge"), modified for Conservative PC to check noncolliders against recorded noncolliders before orienting.

Rule R4 is only performed if knowledge is nonempty.
