rda variance partioning in vegan problems
..."pure binary
interactions" of those groups with each other.
My method for partitioning the variance of binary interactions is as
follows:
Inertia of the interaction of water chemistry and geography = inertia of the
combined effect (conditioned on the remaining groups) - Inertia of just
Waterchemistry - inertia of just geography.
When I do this for each combination two problems arise:
1. I get small negative numbers when 0 should be the lowest possible number.
Does this occur because of internal rounding in the RDA code, or is there
something else going on? (If Total inertia is 9 and explainabl...
