public boolean equals(Clusters cs)

Returns true of cs==this, false otherwise

Specified by:

equals in interface SimpleClusters

toXMLString

public String toXMLString(DataCollection dbm)

Returns XML String representation of Clusters

Specified by:

score in interface SimpleClusters

pr_w_d

public Matrix pr_w_d()

returns the smoothed probability matrix

Specified by:

pr_w_d in interface SimpleClusters
