Sensitivity to Omitted Variable Bias: Coefficients of Proportionality
| Max R-square | Caregiving → Reward | Reward → EF | Caregiving → EF |
|---|---|---|---|
| .1 | 0.43 | - | - |
| .2 | 0.20 | - | - |
| .3 | 0.13 | - | - |
| .7 | - | 0.46 | 0.12 |
| .8 | - | 0.39 | 0.10 |
| .9 | - | 0.34 | 0.09 |
Note: EF refers to executive functions. The reported values indicate the coefficient of proportionality for each regression model. The coefficient of proportionality indicates the proportion of bias from unobserved variables needed to nullify each result.
