Methods in weka.classifiers.bayes.net with parameters of type BayesNet

void	MarginCalculator.calcFullMargins(BayesNet bayesNet)
void	MarginCalculator.calcMargins(BayesNet bayesNet) Calc marginal distributions of nodes in Bayesian network Note that a connected network is assumed.
double	BIFReader.divergence(BayesNet other) calculates the divergence between the probability distribution represented by this network and that of another, that is, \sum_{x\in X} P(x)log P(x)/Q(x) where X is the set of values the nodes in the network can take, P(x) the probability of this network for configuration x Q(x) the probability of the other network for configuration x
int	BIFReader.extraArcs(BayesNet other) Count nr of exta arcs from other network compared to current network Note that an arc is not 'extra' if it is reversed.
int	BIFReader.missingArcs(BayesNet other) Count nr of arcs missing from other network compared to current network Note that an arc is not 'missing' if it is reversed.
boolean[][]	MarginCalculator.moralize(BayesNet bayesNet) moralize DAG and calculate adjacency matrix representation for a Bayes Network, effecively converting the directed acyclic graph to an undirected graph.
void	MarginCalculator.process(boolean[][] bAdjacencyMatrix, BayesNet bayesNet)
int	BIFReader.reversedArcs(BayesNet other) Count nr of reversed arcs from other network compared to current network
void	BIFReader.Sync(BayesNet other) synchronizes the node ordering of this Bayes network with those in the other network (if possible).
