weka.classifiers.functions.IsotonicRegression
public class IsotonicRegression
Learns an isotonic regression model. Picks the attribute that results in the lowest squared error. Missing values are not allowed. Can only deal with numeric attributes.Considers the monotonically increasing case as well as the monotonicallydecreasing case
Valid options are:-D If set, classifier is run in debug mode and may output additional info to the console
