Factor relationships | Mean |
|---|---|
q(X1 ∩ X2) < Min(q(X1), q(X2)) | Weaken-nonlinear: Effect of a single variable is nonlinearly weakened by the interaction of two variables. |
Min (q(X1), q(X2)) < q(X1 ∩ X2) < Max (q(X1), q(X2)) | Weaken-univariate: Effect of single variables are univariably weakened by the interaction. |
q(X1 ∩ X2) > Max(q(X1), q(X2)) | Enhance-bivariate: Effect of single variables are bivariably enhanced by the interaction. |
q(X1 ∩ X2) = q(X1) + q(X2) | Independence: Effect of the variables are independent. |
q(X1 ∩ X2) > q(X1) + q(X2) | Nonlinear enhance: Effect of the variables are nonlinearly enhanced. |
