How to a redundancy analysis（RDA） with matlab,can somebody help me out with a step by step example？

The "Fathom Toolbox for Matlab" performs classical RDA as well as distance-based RDA. Check out the demonstration files included with the toolbox in the examples folder.

Hi, Well its quite easy if you have the Statistical Toolbox. All the required data for Redundancy Analysis can be obtained by using pcacov,mvregress or regress. Using this you can calculate the ordination of dependent and independent variables. For canonical eigen vectors you can also use SVD to perform PCA. The code is pretty easy and straightforward. This is what I am using. If you find anything easier, let me know :P

Cheers!

But how this one helps you in finding RDA? pcacov is different from the RDA results that I am getting using R. Is there any way to find RDA using matlab? Thank you!
