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.
