All Implemented Interfaces:

Serializable, Cloneable, MultiLabelClassifier, MultiLabelDrawable, weka.classifiers.Classifier, weka.core.BatchPredictor, weka.core.CapabilitiesHandler, weka.core.CapabilitiesIgnorer, weka.core.CommandlineRunnable, weka.core.OptionHandler, weka.core.Randomizable, weka.core.RevisionHandler, weka.core.TechnicalInformationHandler

public class PCC
extends CC
implements weka.core.TechnicalInformationHandler

PCC.java - (Bayes Optimal) Probabalistic Classifier Chains. Exactly like CC at build time, but explores all possible paths as inference at test time (hence, 'Bayes optimal').
This version is multi-target capable.
