* Add remedian statistic - [http://www.agoras.ua.ac.be/abstract/Remrob90.htm The
Remedian: a Robust Averaging method for Large Data Sets]
* Add population variance and standard deviation statistic.
* Add 0-1 random number generators. -- Not sure what is being requested here.
RandomData.nextInt(0, 1) will generate random 0-1 values. Are we talking about random
binary strings?
+ * I assumed this item meant "implement good random number generators, e.g., like those
described in ''Numerical Recipes'' or Knuth". -- AlChou
Interestingly, as of 1.2 at least, the JDK-supplied PRNG is Knuth's 3.2.1
(linear congruential). I am +1 for adding additional PRNGs, but I would
also recommend that if we do that we also include benchmark tests (like
the ones here: http://csrc.nist.gov/rng/SP800-22b.pdf), performance
metrics and clear documentation indicating what the relative strengths /
weaknesses of the additional PRNGs are.
* Add sparse matrix implementation.
* Add a fraction type - Can start with implementation contributed to [lang] here

* Add submatrix accessors - [http://issues.apache.org/bugzilla/show_bug.cgi?id=30896]
