As Paul has already said, there is quite a lot of work already done in this
area: Eric Niebler's accumulator and time series lib's handle a lot of the
data collection / descriptive statistic calculation tasks, and the
Math/Distributions library provides all the underlying math code needed to
perform tests etc as well as some fairly comprehensive examples of doing so.

There is still a need to tie some of this together with some high level
interfaces for ANOVA and hypothesis testing etc though should you wish to
rise to the challenge :-)

HTH, John.
