I am having a look at the computations of p-values and quantiles which
depend on the incomplete beta function at present. I hope to have a
better set of functions in place by weeks end. I may need a tester or
two to really exercise the new ones. I'm also looking at the whole
math library to see exactly how much work a proper handling of Inf, NaN
and NA might involve.
