class	NumericPrediction Encapsulates an evaluatable numeric prediction: the predicted class value plus the actual class value.

Methods in weka.classifiers.evaluation that return Prediction

Modifier and Type	Method and Description
Prediction	EvaluationUtils.getPrediction(Classifier classifier, Instance test) Generate a single prediction for a test instance given the pre-trained classifier.

Methods in weka.classifiers.evaluation that return types with arguments of type Prediction

Modifier and Type	Method and Description
ArrayList<Prediction>	EvaluationUtils.getCVPredictions(Classifier classifier, Instances data, int numFolds) Generate a bunch of predictions ready for processing, by performing a cross-validation on the supplied dataset.
ArrayList<Prediction>	EvaluationUtils.getTestPredictions(Classifier classifier, Instances test) Generate a bunch of predictions ready for processing, by performing a evaluation on a test set assuming the classifier is already trained.
ArrayList<Prediction>	EvaluationUtils.getTrainTestPredictions(Classifier classifier, Instances train, Instances test) Generate a bunch of predictions ready for processing, by performing a evaluation on a test set after training on the given training set.
