Bray-curtis dissimilarities
WebSep 1, 2024 · By suggesting an additive decomposition formula for the Bray-Curtis coefficient we derive a general formula of dissimilarity, which includes the Canberra distance and the Bray-Curtis dissimilarity as special cases. A similar general formula is also proposed for the Marczewski-Steinhaus coefficient. WebBray-Curtis dissimilarity is calculated as: In our example above the blue, yellow, and orange species are shared between the two samples. To calculate Cij, we sum up the lesser of those species. Cij = 5 (blue) + 3 (yellow) + 5 (orange) = 13 Si (sample A) = 13 + 3 + 6 = 22 Sj (sample B) = 5 + 5 + 5 + 5 + 4 = 24
