All statistical methods offered by Canoco for Windows 4.5 are available, such as DCA, CA, CCA, DCCA, PCA, and RDA methods - including their partial variants, with Monte Carlo permutation tests for constrained ordination methods, offering appropriate permutation setup for data coming from non-trivial sampling designs.
The above snapshot shows the Analysis Setup Wizard at the page where the type of permutation test is chosen. Here the user is selecting which covariates define permutation blocks. Additionally, permutations for hierarchical (split-plot / repeated-measures) design were selected and the hierarchy must be characterized on the following wizard page.
