Appendix 2.
Corr(X.R) | Corr(Z,R) | β0 | β1 | β2 |
---|---|---|---|---|
Low | Low | −1.40 | 0.05 | 0.05 |
Medium | −3.20 | 0.06 | 0.22 | |
High | −21.35 | 0.13 | 1.90 | |
Medium | Low | −3.20 | 0.22 | 0.06 |
Medium | −5.05 | 0.23 | 0.23 | |
High | −30.90 | 0.64 | 2.32 | |
High | Low | −21.35 | 0.13 | 1.90 |
Medium | −30.90 | 2.32 | 0.64 | |
High* | −64.20 | 3.10 | 3.10 |
In this case the high level of Corr(X,R) and Corr(Z,R) is High ≈ 0.54.
