Interesting idea, but I don't see much that can be abstracted. Basically,
TestStatistic provides test statistics and computes p-values for
Chi-Square and t-tests. The only thing common among these is that the
tests are statistical tests and all that could be abstracted would be the
p-value computation, which is not much IMHO. I am interested in what
others think, though.
Have a look at the new interfaces after I split them out. I am going to
slip support for chi-square tests for independence in two-way tables into
the chi-square stuff to round out that interface.
