Bray-curtis ordination
WebThe Bray-Curtis distance is a favorite for community ecologists to describe similarity in species composition in sample plots. The Bray-Curtis distance is a very robust distance measure. If you have an intuitive sense of similarity of your study subjects (or communities) spot-check the B-C distance matrix. Webtotal of eight ordination techniques to be tested: 1) Bray-Curtis with coefficient of community, 2) Similarity projection with coefficient of community, 3) Bray-Curtis with …
