Class ComputeDeltaH  

java.lang.Object
  riso.apps.ComputeDeltaH

---

public class ComputeDeltaH

extends java.lang.Object

An instance of this class is a helper to compute the difference in entropy from first argument of the constructor (some distribution) to the second (some other distribution). Typically the first distribution is a prior distribution and the second is the posterior over the same variable as the prior; the entropy of the first is generally greater than the second, and so the value returned by do_compute_delta_h is generally positive.
