Method Detail

getClassReferenceVector

public HistogramCategorical getClassReferenceVector(AttributeCategorical sourceAttrib,
                                                    int sourceAttribValue,
                                                    java.util.List<EdgeType> path,
                                                    boolean normalized)

Get the class reference vector from the graph for this attribute.

Parameters:

sourceAttrib - the source attribute for the vector.

sourceAttribValue - the value the source attribute must have.

path - the list of EdgeTypes to follow in the path when creating the vector.

normalized - if true, the results will be normalized.

Returns:

a HistogramCategorical containing the reference vector.

getUnconditionalReferenceVector

public HistogramCategorical getUnconditionalReferenceVector(java.util.List<EdgeType> path,
                                                            boolean normalized)

Get the unconditional reference vector from the graph for this attribute.

Parameters:

path - the list of EdgeTypes to follow in the path when creating the vector.

normalized - if true, the results will be normalized.

Returns:

a HistogramCategorical containing the reference vector.

getMode

public int getMode()

Get the mode value this Graph has for this field.

Returns:

the mode value this Graph has for this field.
