Subject: partition residuals in a constrained ordination
In-Reply-To: <ecf120f78c5e4745b45d7111e7b11c31@wcl.ac.at>
Hei list,
is there an approved way how to partition variance into explained vs unexplained at the level of sites?
After performing a constrained ordination (CCA or dbRDA) I want to check if explained variance varies in a systematic way along given gradient, in a univariate analysis, like plotting the absolute residuals of a regression analysis along a given gradient.
I've tried using rstandard in vegan, but am not sure this allows to partition like in a lm (TSS = RSS + ESS).
thanks for suggestions
Robert
