Principal coordinates analysis (PCoA; also known as metric multidimensional scaling) summarises and attempts to represent inter-object (dis)similarity in a low-dimensional, Euclidean space ( Figure 1; Gower, 1966). In addition to creating it in Plotly, I've published it online using Displayr, which is what allows you to interact with it even though it is in a web page.It's free to do this; you just click Insert > R Output, paste in the R code, press CALCULATE, and then either choose Export > Web Page, or Export > Embed > Embed to embed it in another document or page.

Historic and contemporary anthropogenic effects on granulometry and species composition detected from sediment cores and death assemblages, Nelson Bays, Aotearoa-New Zealand. Introduction Correspondence analysis (CA;Benz ecri1973) is a multivariate descriptive method based on a data matrix with non-negative elements and related to principal component analysis (PCA). Canonical tests using permutations are also given, and we show how the method can be used (1) to place a new observation into the canonical space using only interpoint dissimilarities, (2) to classify observations and obtain misclassification or residual errors, and (3) to correlate the original variables with patterns on canonical plots. Long-term river management legacies strongly alter riparian forest attributes and constrain restoration strategies along a large, multi-use river. Recent land‐use changes affect stream ecosystem processes in a subtropical island in Brazil. Ecology, 84: 511–525. Redundancy analysis (RDA) is the canonical version of principal component analysis (PCA). These are finally arranged in such a way that the first PC gets to explain lots of variation. Anderson and Willis advocate to use the number of principal coordinate axes that result in the best prediction of group identities of the sites.

Regression analysis quantifies a relationship between a predictor variable and a criterion variable by the coefficient of correlation r , coefficient of determination r 2 , and the standard regression coefficient β .
