Subject: Re: [DNA] Any feedback on the RCC method of TMRCA estimates?

I just want the formula. Why would anyone use a method if they could not
write down the formula.
I'll read the paper if the formula has any plausibility.

[[ Two haplotypes are h1[i] and h2[i] with i running from 1 to 37. Would
you please convert your comment into the formula for RCC? Excel's correl
function involves some average quantities as well as component values. KN]]
