Dear all,
Does anyone knows why the results of a BIOENV (PRIMER v. 6.1.15) are
diferent of the bioenv() + mantel() in vegan? Not the spearman correlation,
indeed the pseudo-p value.
I know that the approach bioenv() + mantel() is biased. So, how the BIOENV
(PRIMER) ends with larger p values (permutated).
Acctualy how the permutation test in BIOENV (PRIMER) is conducted. The user
guide does not make it clear.
Best Wishes,
