> Avoid unexpected errors in EmpiricalDistribution
> ------------------------------------------------
>
> Key: MATH-1279
> URL: https://issues.apache.org/jira/browse/MATH-1279
> Project: Commons Math
> Issue Type: Improvement
> Affects Versions: 3.5
> Environment: Ubuntu 14.04
> Reporter: David Georg Reichelt
> Priority: Trivial
> Fix For: 4.0, 3.6
>
> Original Estimate: 1h
> Remaining Estimate: 1h

> Loading an empirical distributions results in an
> ArrayIndexOutOfBoundsException when giving 0 as bin size, for example in:
> double values[] = new double[] { 1, 2 };
> EmpiricalDistribution distribution = new EmpiricalDistribution(0);
> distribution.load(values);
> To keep the error more understandable to the user, it would be nice if an
> RuntimeException or something like this would be thrown when initializing the
> EmpiricalDistribution with 0 bins. Especially when following the rule of
> thumb that there should be values size / 10 bins, it is hard to find out that
> the error is caused by a wrong bin size and not by some error in the
> load-call.
