Class SvarSetEndpointStrategy

java.lang.Object

edu.cmu.tetrad.search.utils.SvarSetEndpointStrategy

All Implemented Interfaces:

SetEndpointStrategy

public class SvarSetEndpointStrategy
extends Object
implements SetEndpointStrategy

The SvarSetEndpointStrategy class implements the SetEndpointStrategy interface and provides a strategy for setting the endpoint of an edge in a graph. It uses the IndependenceTest and Knowledge classes for conducting conditional independence testing and causal discovery.

The idea is, whenever an endpoint is set by FciOrint, we should check if there are similar pairs in the graph that should be oriented in the same way.
