Jared Becksfort updated MATH-815:
---------------------------------

    Attachment: mvn4.zip

Removed two public functions from MultivariateNormalDistributions.java.  I am \
reattaching all the files so you don't have to sort through the latest changes. They \
go in the distributions src/main and src/test packages.

> Key: MATH-815
> URL: https://issues.apache.org/jira/browse/MATH-815
> Project: Commons Math
> Issue Type: New Feature
> Reporter: Jared Becksfort
> Priority: Minor
> Attachments: MultivariateNormalDistribution.java, \
> MultivariateNormalDistributionTest.java, mvn.tgz, mvn2.tgz, mvn3.zip, mvn4.zip, \
> patch 
> Original Estimate: 1m
> Remaining Estimate: 1m
> 
> I will submit a class for Multivariate Normal Distributions.  Not sure if it will \
> allow sampling initially.
> > Hello,
> > 
> > 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. 
> > Thanks,

> 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.
