I see Mark voted for > "test", but -- perhaps because I've never done much statistics -- that makes me > think that I'm looking at a JUnit "tests" directory tree.

I'm not too picky here, I just picked test because its shorter, inference is more descriptive too. Along the same lines "distributions" could be confused with the the generic idea of a "distribution" of packages directory, maybe "probability is better there? Maybe it should be organized more along the following lines? o.a.c.m.stat.probability... o.a.c.m.stat.univariate... o.a.c.m.stat.multivariate... o.a.c.m.stat.inference... > While you're moving TestStatistic, I noticed two typos in the Javadoc for > chiSquare( double[, double[] ): "freqeuncy" and "counds". -- Mark R.
