Hi All

I've had a look at some specific aspects of the stats paper and have a
draft paper on that. It's at
https://isocpp.org/files/papers/D2376R0.pdf "Comments on Simple Statistical
Functions (p1708r4): Contracts, Exceptions and Special cases".

I hope it is of use. I don't currently plan to update it more, except
perhaps some fixups. Any discussion of quantiles and medians was excluded
to keep it focused. Oh, and I just saw the mail from Oleksandr Koval which
has some points that intersect with some of my writeup.

For info, I'm working on a little extension to nth_element, taking a range
of nths instead of just one. Although it's a general purpose algorithm and
not a statistical function I was inspired to put it out there after reading
and discussing p1708.

of nth_element"
