Renkonen similarity index explained

p _{i} = n _{i/\sum{n} _{i}} of individuals of composite species. It was developed by the botanist Olavi Renkonen and published in 1938.^[1] P = \sum{min(p _{1;p} _{2)}} ,p _{1} - percentage structure of one set,p _{2} - percentage structure of second set.

The codomain of this distance function ranges from 1 (identical proportional abundances) to 0 (no taxa shared).
