[jira] [Resolved] (MATH-973) Geometric distribution support

     [ https://issues.apache.org/jira/browse/MATH-973?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Thomas Neidhart resolved MATH-973.
----------------------------------

       Resolution: Fixed
    Fix Version/s: 4.0

Thanks for the patch and report!

Applied it together with minor changes in r1480064.
I also changed the input validation check for the probability to (0, 1] as the geometric distribution is defined for this range, although a value of 1 will not produce very useful results.
