Thanks for the tip. I was not aware of IntelliJ but I'll certainly look 
into it.

OK, after fidgeting with NetBeans for too long without results, I went 
with Phil's suggestion and just used subversion at the command prompt. 
It was much easier than trying to configure NetBeans.


I uploaded the patch this evening. It includes two new classes 
StorelessCovariance.java and StorelessCovarianceMatrix.java. I also 
included a new test class StorelessCovarianceTest.java.


Interestingly, the one-pass algorithm is slightly less accurate than the 
two-pass algorithm. I had to reduce the tolerance from 10E-9 to 10E-7 in 
order for tests to pass with the Longley data. The tolerance was not 
changed for the Swiss data. It remained 10E-13 for the Swiss data.

Re: [math] StorelessCovariance

[Greg Sterijevski]

I am building in Netbeans and I believe that Luc is correct. I initially had
problems until I included the junit.jar. (junit-4.8.2.jar)


PS What is your approach to the covariance matrix? Are you building a sum of
squares matrix or keeping updates of the mean, ... etc?

Do you have a complete implementation of JUnit in your classpath or only 
the top level API ?


It seems similar to this:

and hence elated to API and implementation separation.


Apache Commons Math does not have any runtime dependency and the only 
test time dependency is JUnit.

First of all, THANKS for working on this!

This may not be what you want to hear or the fashionable response,
but I personally never use IDE integrated thingies for exactly this
kind of reason.  Most likely you have some kind of classpath or
compiled class cleanup problem.  Try cleaning everything and
starting with a fresh checkout and also checking that the IDE is not
bringing in an old [math] jar somehow.

As I said, because of this kind of silliness, I always just run "svn
co" or "svn up" from the command line and then "mvn clean test" from
the checked out trunk.  Then "svn diff > newPatch" to create patches
or inspect changes before committing.  Using -Dtest=ClassNameOfTest
is convenient if you don't want to run all of the tests.
