Thomas Neidhart updated MATH-644:
---------------------------------
Fix Version/s: (was: 2.2)

Updated fix version as there will be no 2.2.1
> for the class of hyper-geometric distribution, for some number the method
> "upperCumulativeProbability" return a probability greater than 1 which is
> impossible.

> Fix For: 3.1

>
> In windows 7, I used common.Math library. I used class
> "HypergeometricDistributionImpl" and method "upperCumulativeProbability" of
> zero for distribution and the return value is larget than 1. the following
> code is working error.
> HypergeometricDistributionImpl u = new
> HypergeometricDistributionImpl(14761461, 1035 ,1841 );
> System.out.println(u.upperCumulativeProbability(0))
