Bray-curtis metric
WebPrincipal coordinates analysis (PCoA) plots were calculated from Bray–Curtis metric distances to evaluate the composition of the community, and the results revealed a clear separation between each group (Fig. 4 A). The system clustering tree indicated marked differences among the four groups. Webterm Bray-Curtis (Bray & Curtis 1957), used as a mea-sure of resemblance between samples in analyses of multivariate data. Yoshioka (2008) cites Goodall (1978) ...

WebNov 18, 2024 · Both methods may be implemented with any dissimilarity metric. Among abundance-based beta diversity indices, Bray-Curtis is the most common choice for count data [ 16, 17 ]. The most widely applied phylogenetic beta diversity indices are UniFrac-type metrics [ 17 – 19 ]. WebCommon indices include Bray-Curtis, Unifrac, Jaccard index, and the Aitchison distance. Each of these (dis)similarity measures emphasizes different aspects. For example, UniFrac incorporates phylogenetic …
