Class CorrelationCalc

java.lang.Object
  edu.iastate.metnet.metaomgraph.CorrelationCalc

public class CorrelationCalc
extends java.lang.Object

Calculates Pearson Correlations for sets of data. Initialize it with data set A, and you can calculate P(A,B), P(A,C), etc. If you want to calculate P(B,C), you'll need to create a new calculator.
