Class MnlrScore

java.lang.Object

edu.cmu.tetrad.search.work_in_progress.MnlrScore

All Implemented Interfaces:

Score

public class MnlrScore
extends Object
implements Score

Implements a mixed variable polynomial BIC score for fGES.

As for all scores in Tetrad, higher scores mean more dependence, and negative scores indicate independence.
