    @FSchumacher thank you for the remark, it is fixed now
    
    @pmouawad DescriptiveStatistics uses legacy percentile calculation method by default,
which is Linear Interpolation Third Variant C=0
    To fix the test please add these lines after the loop
    ```
    statistics.setPercentileImpl((new Percentile()).withEstimationType(Percentile.EstimationType.R_1));
    for (int i=1; i<=100; i++) assertEquals(statistics.getPercentile(i), calc.getPercentPoint(i
/ 100D), 0.001);
    ```
    I wonder why do we still use **org.apache.jorphan** having such a powerful math library
as Apache Commons Math.
