> 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
