Dilemma in multivariate testing in ecology: My test is better than yours.

Snippets from papers that conclude one multivariate test is better than others for variance partitioning. Remember that these are just snippets and does not relay the overall message. However, if i list a pro here, you can be sure that there is a con somewhere else in the paper (follow link) and vice versa. At the end of the day, none of the tests are perfect, but are the best if used and interpreted as per authors’ manual.

  • “Regardless of the philosophical merits of distance-based or raw-data based methods for testing beta diversity (Legendre, Bor card & Peres-Neto 2005; Tuomisto & Ruokolainen 2006), it is clear that correlations based on distance matrices are inferior to RDA for modelling spatial patterns. ” from link1
  • “The inflation of R2 statistics and the irregularities in the forward selection of eigenvectors indicate that the PCNM and MEM methods are unstable and vulnerable to statistical artefacts “link1
