[jira] [Created] (STATISTICS-60) Update Pareto distribution sampler to use Commons RNG 1.6

Alex Herbert created STATISTICS-60:
--------------------------------------

             Summary: Update Pareto distribution sampler to use Commons RNG 1.6
                 Key: STATISTICS-60
                 URL: https://issues.apache.org/jira/browse/STATISTICS-60
             Project: Commons Statistics
          Issue Type: Task
          Components: distribution
    Affects Versions: 1.0
            Reporter: Alex Herbert


The Pareto distribution uses a wrapped RNG to create the InverseTransformParetoSampler from Commons RNG. This is done to manipulate the range of p-values that are inverted during sampling based on the shape parameter.

This same manipulation has been implemented in Commons RNG 1.6 (currently unreleased). When the Statistics dependency on RNG is updated then the modifications in the ParetoDistribution can be removed.
