>         Environment: Windows 7
>            Reporter: Richard Brunauer

> 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.
