Class StabilityUtils

java.lang.Object

edu.pitt.csb.stability.StabilityUtils

public class StabilityUtils
extends Object

Runs a search algorithm over a N subsamples of size b to asses stability as in "Stability Selection" and "Stability Approach to Regularization Selection"

This is under construction...likely to be buggy
