Subject [jira] [Created] (MATH-1133) NaNStrategy for UnivariateStatistic and friends
Date Fri, 27 Jun 2014 13:24:24 GMT
Sergei Lebedev created MATH-1133:

             Summary: NaNStrategy for UnivariateStatistic and friends
                 Key: MATH-1133
             Project: Commons Math
          Issue Type: Improvement
            Reporter: Sergei Lebedev
            Priority: Minor

In the current implementation univariate statistics don't allow to specify NaN behaviour.
For instance, the following code simply yields NaN as the result.

Mean mean = new Mean();
System.out.println(mean.getResult());  // prints 'NaN'.

Is it possible to parametrize all available statistics by NaNStrategy with the default behaviour
being a no-op?
