public class MILRARITH

extends MIClassifier

implements weka.core.OptionHandler

Using collective assumption, arithmatic average of the posteriors of instances inside a bag is taken. Valid options are:

-D
Turn on debugging output.

-P precision
Set the precision of stopping criteria in Newton method.

-R ridge
Set the ridge parameter for the log-likelihood.
