> Benchmark statistic generation time using array input

> Key: STATISTICS-89
> URL: https://issues.apache.org/jira/browse/STATISTICS-89
> Project: Commons Statistics
> Issue Type: Task
> Components: descriptive
> Reporter: Alex Herbert
> Priority: Minor
> Fix For: 1.2

> Attachments: array.png, array_vs_range.png

>
> Update the JMH benchmark for creation of a statistic from an array to support
> the current implementations. (Note: At present the benchmark uses a simple
> sum implementation to test different loop/stream methods.)
> Investigate the performance of creation of statistics from a sub-range of an
> array. Currently this is not possible and requires a copy of the sub-range,
> e.g. to get the mean of the last half of an array:
> {code:java}
> double[] x = ...
> int from = x.length >> 1;
> int to = x.length;
> Mean m = Mean.of(Arrays.copyOfRange(x, from, to))
> {code}
