Gilles Sadowski resolved MATH-1503.
-----------------------------------
Resolution: Won't Do
Thanks for the report. I made the change in the ["Commons Statistics"
project|http://commons.apache.org/proper/commons-statistics/] where the
distributions now belong (most of the package {{o.a.c.m.stat.distribution}} has
been moved there and will be removed from the next major version of Commons
Math).
You are most welcome to review and test the ported code.
> cumulativeProbability of LevyDistribution returns NaN for values out of
> domain, while others return 0

> Key: MATH-1503

> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 3.6.1
> Reporter: WFR
> Priority: Minor
>
> LevyDistribution.cumulativeProbability returns Double.NaN for values that are
> outside of its domain (x < mu in this case), while GammaDistribution returns
> 0.0 (for x <= 0). Both cases are hard-coded.{color:#ffc66d}
> {color}
> A consistent behaviour would be desirable.
