------------------------------

Hi Bruno.

Thanks for your help.
But it's so sad that you had to spend time looking for clues about an [issue that was solved
9 months ago in the CM fork|https://github.com/Hipparchus-Math/hipparchus/issues/9]. :(

> When I use the Binomial Test, I got p-value > 1 for two sided check.
> Example:
> (new BinomialTest()).binomialTest(200, 200, 0.9950429, AlternativeHypothesis.TWO_SIDED)
== 1.3701357550780435
> In my case, if the expected p-value is 1 (calculated by package in other language, scipy
in this case), the p-value returned could be > 1
