[commons-statistics] Dev suggestions needed

[icewing <ic...@163.com>]

Hi all!


I'm a data analyst working with Java, so I need some libraries for math, especially statistics. I came across the Apache Commons Math library and found that you're working with a new sub-library of statistics. 


I want to make some contribution. I've roughly went through the current commons-math4 and commons-statistics-parent branch. It seems that you've already ported the distribution sub-package from commons.math4.stat, but the other sub-packages, such as descriptive and regression, their porting seems more challenging, as described in ML and jira issues.


From which package do you suggest should I start for the remaining porting, or you think I should post a more specific proposal?


I appreciate your help very much. 


Best,
Tao

IIRC, one concrete conclusion from the last discussion on this topic
(during last year's GSoC) was that the "descriptive" package would
be the easiest to port.
The next one would be "regression", but this involves the issue of
which linear algebra utilities to depend on, and how (that was not
settled IIRC).

Hoping to get confirmation from others.

A novel viewpoint might give new ideas... ;-)

Thanks for your offer!
