Table 3 Interaction relationship between two factors
From: Spatial association between outdoor air pollution and lung cancer incidence in China
Description | Interaction |
|---|---|
q(X1 ∩ X2) < Min(q(X1), q(X2)) | Non-linear weakening |
Min(q(X1), q(X2)) < q(X1 ∩ X2) < Max(q(X1), q(X2)) | Univariate weakening |
q(X1 ∩ X2) > Max(q(X1),q(X2)) | Bivariate enhancement |
q(X1 ∩ X2) = q(X1) + q(X2) | Independent |
q(X1 ∩ X2) > q(X1) + q(X2) | Non-linear enhancement |
