class WRACCMeasure used to measure weighted relative accuracy of 2-class classifier.
This class is also capable of measuring any other rate using get_[measure name] methods of CContingencyTableEvaluation class.
Note that evaluate() should be called first.

Builds a dictionary of all parameters in SGObject as well of those of SGObjects that are parameters of this object. Dictionary maps parameters to the objects that own them.

Creates a clone of the current object. This is done via recursively traversing all parameters, which corresponds to a deep copy. Calling equals on the cloned object always returns true although none of the memory of both objects overlaps.

A deep copy. All the instance variables will also be copied.

Recursively compares the current SGObject to another one. Compares all registered numerical parameters, recursion upon complex (SGObject) parameters. Does not compare pointers!
May be overwritten but please do with care! Should not be necessary in most cases.
