    Redundancy Analysis. As mentioned previously, most of the discussion of CCA pertains to Redundancy Analysis (RDA). However, note that RDA is a linear method. Some of the special properties of RDA include: Since it is a linear method, species as well as environmental variables are represented by arrows.

    This demo shows you step-by-step how to perform a Canonical Correspondence Analysis (CCA) with the Canoco for Windows 4.5 package. Most software components in this package are used in this demo.
    Distance-based redundancy analysis (dbRDA) is an ordination method similar to Redundancy Analysis (rda), but it allows non-Euclidean dissimilarity indices, such as Manhattan or Bray-Curtis distance. Despite this non-Euclidean feature, the analysis is strictly linear and metric. If called with Euclidean distance, the results are identical to rda, but dbRDA will be less efficient.
    The bottom line is that you reduce redundancy when using PCA. Principal Component Analysis Example in ArcGIS. What about elevation, slope and hillshade data? Is there redundancy in these three data sets? Here’s how to run a PCA analysis with elevation, hillshade and slope bands in ArcGIS: 1 Run the «Composite Bands» tool

The purpose of this vignette is to illustrate the use of Redundancy Analysis (RDA) as a genotype-environment association (GEA) method to detect loci under selection (Forester et al., 2018). RDA is a multivariate ordination technique that can be used to analyze many loci and environmental predictors simultaneously.
    What is Redundancy Analysis. Redundancy Analysis (RDA) was developed by Van den Wollenberg (1977) as an alternative to Canonical Correlation Analysis (CCor
