Gilles commented on MATH-944:
-----------------------------
bq. Frequency2
:(
Isn't the patch backwards-compatible with the current version?
As an aside, the class contains methods whose names should be modified
(according to an exchange on the ML).
> Consider making a generic version of class Frequency

> Key: MATH-944
> URL: https://issues.apache.org/jira/browse/MATH-944
> Project: Commons Math
> Issue Type: Improvement
> Affects Versions: 3.1
> Reporter: Thomas Neidhart
> Priority: Minor
> Fix For: 4.0
>
> Attachments: Frequency.java
>
>
> The current version of the Frequency class is quite complex, as it has to
> handle different input values and does a lot of casting.
> The class is also not very safe in the sense that adding different data types
> will lead to runtime exceptions.
> The class could be simplified by introducing a generic version. The only
> downside so far is that the current version treats ints and longs together,
> which would not be possible with a generic version.
