Phil Steitz updated MATH-474:
-----------------------------

    Fix Version/s: 3.0

+1 for this enhancement.  Thanks in advance for the patch.  Make sure to document the fact that the freqs being merged need to contain only mutually comparable values.  If and when we address MATH-474, that requirement will only apply to merging "full" Frequency instances.

> I'd like to propose an enhancement to org.apache.commons.math.stat.Frequency.  I need to "merge" multiple Frequency objects, and it would be great if Frequency had inherent support for this, such as:
> public void merge(Frequency other);
> public void merge(Collection<Frequency> others);
> I'd be happy to submit a patch if that would help...
