Alex Herbert resolved STATISTICS-90.
------------------------------------
Fix Version/s: 1.2
Resolution: Implemented
> Support statistic creation using an array range
> -----------------------------------------------
>
> Key: STATISTICS-90
> URL: https://issues.apache.org/jira/browse/STATISTICS-90
> Project: Commons Statistics
> Issue Type: New Feature
> Components: descriptive
> Affects Versions: 1.1
> Reporter: Alex Herbert
> Priority: Minor
> Fix For: 1.2
>
>
> Add support for using part of an array to create statistics:
> {code:java}
> double[] x = ...
> int from = ...
> int to = ...
> Min.ofRange(x, from, to);
> DoubleStatistics.ofRange(EnumSet.of(Statistic.MIN), x, from, to);{code}
> This change should have no impact on performance for full length arrays and
> improve memory consumption by avoiding array copies on sub-ranges. Results
> from STATISTICS-89 indicate a non-negligible performance gain for fast
> computing statistics.
> Note: Support for sub-ranges is present in the Commons Math
> UnivariateStatistic interface. This change will allow supporting replacement
> of the Math API with Statistics.
