title: The Hellinger distance as used for the representation of serological ABO distances among earlier human populations.
abstract: The Hellinger (arccos) distance is examined for the purpose of demonstrating to what extent it represents the differences among populations. When the Hellinger distance is employed to estimate gene frequencies, a result very similar to that of the maximum likelihood (Bernstein) method can be gained. It is pointed out that in palaeoserological examinations the Dobson/Ikin method usually mentioned as Fisher method is not equivalent to the Bernstein method.
