Table 4 Types of two-factor interactions.
From: Spatiotemporal variation and driving forces of carbon storage in the Fuhe river basin, China
Judgment basis | Interaction Types |
|---|---|
q(X1∩X2)< Min[q(X1),q(X2)] | Nonlinear strengthening weakened |
Min[q(X1),q(X2)]< q(X1∩X2)< Max[q(X1),q(X2)] | Single factor nonlinear weakening |
q(X1∩X2)> Max[q(X1),q(X2)] | Two-factor enhancement |
q(X1∩X2) = q(X1) + q(X2) | Independence |
q(X1∩X2)> q(X1) + q(X2) | Nonlinear enhancement |
