             Summary: Update LargeMeanPoissionSampler to use the ZigguratExponentialSampler
                 Key: RNG-150
                 URL: https://issues.apache.org/jira/browse/RNG-150

          Issue Type: Improvement
          Components: sampling
    Affects Versions: 1.3

The LargeMeanPoissionSampler uses a standard exponential deviate. This can be changed from the AhrensDieterExponentialSampler to the ZigguratExponentialSampler which is 4x faster.
