> 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?
