--------------------------------------

Gilles,

I just got back in town.  I will try to modify the test tomorrow and submit.

> > I have implemented some classes for multivariate Normal distributions, multivariate normal mixture models, and an expectation maximization fitting class for the mixture model.  I would like to submit it to Apache Commons Math.  I still have some touching up to do so that they fit the style guidelines and implement the correct interfaces.  Before I do so, I thought I would at least ask if the developers of the project are interested in me submitting them.

> Dear Jared,
> Yes, that would be very nice to have such an addition! Remember to also include unit tests (refer to the current ones for examples). The best would be to split a submission up into multiple minor ones, each covering a natural submission (e.g. multivariate Normal distribution in one submission), and create an issue as described at http://commons.apache.org/math/issue-tracking.html .
> If you run into any problems, please do not hesitate to ask on this mailing list.
> Cheers, Mikkel.
