public abstract class RegressionGenerator
extends DataGenerator

Abstract class for data generators for regression classifiers.

Example usage as the main of a datagenerator called RandomGenerator:

 public static void main(String[] args) {
   try {
     DataGenerator.makeData(new RandomGenerator(), args);
   } 
   catch (Exception e) {
     e.printStackTrace();
     System.err.println(e.getMessage());
   }
 }
