Detailed Description

A class representing a set of BCModels.

Author: Daniel Kollar; Kevin Kröninger

Version: 1.0

Date: 08.2008 This class represents a manager for BCModels. It handles common data sets and performs operations on BCModels simultaneously. Model comparsion in terms of a posteriori probabilities is only possible with this class.
