Directly known subclasses:

public static class CbsModel
extends CopyNumberSegmentationModel

This class represents the Circular Binary Segmentation (CBS) model [1].

Usage

CbsModel(cesTuple=NULL, ..., seed=NULL)

Arguments

cesTuple	A CopyNumberDataSetTuple.
...	Arguments passed to the constructor of CopyNumberSegmentationModel.
seed	An (optional) integer that if specified will (temporarily) set the random seed each time before calling the segmentation method. For more information, see segmentByCBS().
