public class Experiment extends java.lang.Object implements java.io.Serializable, OptionHandler, RevisionHandler

-T <arff file> The dataset to run the experiment on. (required, may be specified multiple times)
-P <class name> The full class name of a ResultProducer (required). eg: weka.experiment.RandomSplitResultProducer
-D <class name> The full class name of a ResultListener (required). eg: weka.experiment.CSVResultListener
-N <string> A string containing any notes about the experiment. (default none)
Options specific to result producer weka.experiment.RandomSplitResultProducer:
-P <percent> The percentage of instances to use for training. (default 66)
-D Save raw split evaluator output.
-O <file/directory name/path> The filename where raw output will be stored. If a directory name is specified then then individual outputs will be gzipped, otherwise all output will be zipped to the named file. Use in conjuction with -D. (default splitEvalutorOut.zip)
-W <class name> The full class name of a SplitEvaluator. eg: weka.experiment.ClassifierSplitEvaluator
-R Set when data is not to be randomized and the data sets' size. Is not to be determined via probabilistic rounding.
Options specific to split evaluator weka.experiment.ClassifierSplitEvaluator:
-W <class name> The full class name of the classifier. eg: weka.classifiers.bayes.NaiveBayes
-C <index> The index of the class for which IR statistics are to be output. (default 1)
-I <index> The index of an attribute to output in the results. This attribute should identify an instance in order to know which instances are in the test set of a cross validation. if 0 no output (default 0).
-P Add target and prediction columns to the result for each fold.
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
All options after -- will be passed to the result producer.- Version:
