  Full name of base classifier.
  (default: weka.classifiers.rules.ZeroR)
         Options specific to classifier weka.classifiers.rules.ZeroR:
 
         -D
  If set, classifier is run in debug mode and
  may output additional info to the console
         -S <sint>
  Number of regressions
  (default: 10)
 
         -P <int>
  Percent sample size
