Phil Steitz commented on MATH-1086:
-----------------------------------
Thomas - agree that is a nice design. I would be +1 for this change, but it
would be nice to then expose static methods somewhere to just get the
intervals. Not sure what the best place for these would be. Maybe best to
take this to commons-dev.

> Key: MATH-1086
> URL: https://issues.apache.org/jira/browse/MATH-1086
> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 3.3
> Reporter: Siarhei Khamenka
> Fix For: 3.3
>
>
> It looks like BinomialConfidenceInterval#getWilsonScoreInterval produces not
> accurate results for interval lower bound.
> E.g. for input (10,9,0.95) it returns 0.818 instead of 0.596;
> for input (10,10,0.95) it returns 0.856 instead of 0.722.
> Used also
> http://epitools.ausvet.com.au/content.php?page=CIProportion&SampleSize=10&Positive=9&Conf=0.95&Digits=3
> and http://www.measuringusability.com/wald.htm to verify it.
