java.lang.Objectweka.experiment.ClassifierSplitEvaluator
A SplitEvaluator that produces results for a classification scheme
on a nominal class attribute.
-W classname
Specify the full class name of the classifier to evaluate.
-C class index
The index of the class for which IR statistics are to
be output. (default 1)
-I attr index
The index of an attribute to output in the tresults. This
attribute should identify an instance in order to know
which instances are tested in a fold (default 1).
-P
Add the prediction and target columns to the result file for each fold.

Specify the full class name of the classifier to evaluate.
-C class index
The index of the class for which IR statistics are to
be output. (default 1)
