Bray-curtis similarity index

WebThe statistical analysis of the Bray–Curtis similarity and MDS of the calculated ecological water quality index between the river and channels showed a very low stress value (0.05), indicating that the ordination space between samples exhibited a near-perfect representation . WebJul 1, 2024 · BC index is a dissimilarity or similarity index calculated between two rows (or columns). When calculated just for one observation (that is, when indices are equal and the row/column is just duplicated) it will be 0 (if distance) or 1 (if similarity). The linked formula defines a similarity index.
