             Summary: Add a zeta distribution
                 Key: STATISTICS-101
                 URL: https://issues.apache.org/jira/browse/STATISTICS-101
             Project: Commons Statistics
          Issue Type: New Feature
          Components: distribution
    Affects Versions: 1.3
            Reporter: Alex Herbert


The [zeta distribution 
(wikipedia)|https://en.wikipedia.org/wiki/Zeta_distribution] is the large N 
limit of the zipf distribution:

{noformat}
pmf(x) = k^-s / zeta(s)
{noformat}

Where zeta(s) is the Riemann zeta function.

This can be implemented using the Hurwitz zeta function added for the zipf 
distribution in [STATISTICS-100].
