Table 2 Result types of two-factor interactions.
Judgment basis | Interaction type |
|---|---|
q(X1∩X2) < Min(q(X1),q(X2)) | Nonlinear weakening |
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 |
