Reducing Bias Amplification in the Presence of Unmeasured Confounding through Out-of-Sample Estimation Strategies for the Disease Risk Score

Wyss, Richard; Lunt, Mark; Brookhart, M. Alan; Glynn, … - In: Journal of Causal Inference 2 (2014) 2, pp. 131-146

analysis to review and illustrate the process of bias amplification. We show that traditional estimation strategies for the DRS … do not avoid bias amplification when controlling for predictors of treatment. We then discuss estimation strategies for … the DRS that can potentially reduce bias amplification that is caused by controlling both instrumental variables and …
