Class SetAnalysis

java.lang.Object
  lio.population.contchain.SetAnalysis

public class SetAnalysis
extends java.lang.Object

This class deals with a population considering that elements are chains of real values. It allows performing some operations such as getting statistics of different variables, etc.
