Bray-Curtis Dissimilarity
(BCD)/Sorensen Distance
Bray-Curtis is a modified Manhattan measurement,
where the summed differences between the variables
are standardised by the summed variables of the
objects. The general equation of the Bray-Curtis
dissimilarity is:

Bray-Curtis Similarity (BCS)
In the equation dBCD is the Bray-Curtis dissimilarity
between the objects i and j, k is the index of a variable
and n is the total number of variables y. The Bray-
Curtis similarity dBCS is a slightly modified equation. It
can be directly calculated from the dissimilarity value:
dBCS = 1 – dBCD
In opposite to the dissimilarity approach a dBCS value of
0 means a complete absence of relationships.
