Class ClusterSignificance

java.lang.Object

edu.cmu.tetrad.search.utils.ClusterSignificance

public class ClusterSignificance
extends Object

Provides some methods to check significance of clusters for clustering algroithms. It is assumed that for each cluster there is a single latent that is a parent of all the nodes in the cluster. Significance of these models is returned.
