------------------------------------
Summary: NaNStrategy for UnivariateStatistic and friends
Key: MATH-1133
URL: https://issues.apache.org/jira/browse/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.
{code:java}
Mean mean = new Mean();
mean.increment(42);
mean.increment(Double.NaN);
System.out.println(mean.getResult()); // prints 'NaN'.
{code}
Is it possible to parametrize all available statistics by NaNStrategy with the
default behaviour being a no-op?
