             Summary: Update LargeMeanPoissionSampler to use the 
ZigguratExponentialSampler
                 Key: RNG-150
                 URL: https://issues.apache.org/jira/browse/RNG-150
             Project: Commons RNG
          Issue Type: Improvement
          Components: sampling
    Affects Versions: 1.3
            Reporter: Alex Herbert


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