Anatole's method is different than that of the infinite allele model of
Bruce Walsh. Because of this the Std. Dev. or CI will likely be
different between the two methods (one cannot presume they will be the
same). I would suggest understanding Anatole's method to see if you can
come up with the same Std. Dev. that he arrives at. He may be right.
