That is interesting. The first of these, namely sum(|x_i - y_i|) / sum(x_i + y_i) is now better known in ecology as the Bray-Curtis distance. Even more
interesting is the typo in Henry &
Stevens "A Primer of Ecology in R" where the Bray Curtis distance formula is
actually the Canberra
distance (Eq. 10.2 p. 289). There seems to be a certain slipperiness of
definition in this field. Actually, the author is M. H. Henry (Hank) Stevens, not "Henry & Stevens" ... Ben Bolker
