> Key: MATH-1347
> URL: https://issues.apache.org/jira/browse/MATH-1347
> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 3.6
> Environment: Windows 7
> Reporter: Richard Brunauer
> Priority: Trivial
> Labels: documentation
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> The Javadoc entry for Enum Percentile.EstimationType LAGACY uses a wrong equation for variable estimate.
> Explaination in version 3.0, 3.6 source code and 3.6 semantics do an interpolation between two values. The quation for variable estimation has only a ceiling function. This does not match.
