Which results of the standard test for community weighted mean approach are too optimistic?

David Zelený

The relationship between the average height of understory herbs (CWM of species height) and the amount of light passing through the forest canopy (quantified by visually estimated cover of trees and shrubs at each site). If the analysis based on CWM approach was done by a standard parametric test, the result is highly significant (P<0.001). However, the result of the standard test is overly optimistic; the max test, which is the correct test for this analysis, returns considerably less exciting P-value (P=0.052).

Imagine a forest, with trees forming a canopy and herbs growing in the understory.…
