Gilles resolved MATH-747.
-------------------------
Resolution: Won't Fix
Fix Version/s: (was: 2.2.1)
3.0
The code does not exist anymore in "trunk".
> Several Constructors for PoissonDistributionImpl are broken
> -----------------------------------------------------------
>
> Key: MATH-747
> URL: https://issues.apache.org/jira/browse/MATH-747
> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 2.2
> Reporter: Steve Appling
> Priority: Critical
> Fix For: 3.0
>
>
> Only the constructor PoissonDistributionImpl(double) seems to actually work.
> All of the others cause a NullPointerException. The working one creates a
> default NormalDistribution, but all of the others just leave the member
> "normal" set to null and cause an NPE in the constructor.
> I can't even find a work around to construct a PoissonDistributionImpl with
> both a specified mean and an epsilon, since there is no way to set epsilon
> after creation and the constructor PoissonDistributionImpl(double p, double
> epsilon) does not work.
