How to compare instrumental variable and conventional regression analyses using negative controls and bias plots
There is increasing interest in the use of instrumental variable analysis to overcome unmeasured confounding in observational pharmacoepidemiological studies. This is partly because instrumental variable analyses are potentially less biased than conventional regression analyses. However, instrumental variable analyses are less precise, and regulators and clinicians find it difficult to interpre...
متن کاملSelecting on treatment: a pervasive form of bias in instrumental variable analyses.
Instrumental variable (IV) methods are increasingly being used in comparative effectiveness research. Studies using these methods often compare 2 particular treatments, and the researchers perform their IV analyses conditional on patients' receiving this subset of treatments (while ignoring the third option of "neither treatment"). The ensuing selection bias that occurs due to this restriction ...

متن کاملThe Use of Propensity Scores and Instrumental Variable Methods to Adjust For Treatment Selection Bias
Observational studies that lack randomization of subjects into treatment groups must address selection bias to properly estimate the effect of treatment. This paper explores a propensity scoring (PS) method and instrumental variable (IV) method of controlling for treatment selection bias. Included is a discussion of the methods, the advantages and disadvantages of the two methods as well as a c...
متن کاملBias Reduction in Instrumental Variable Estimation through First-Stage Shrinkage
The two-stage least-squares (2SLS) estimator is known to be biased when its first-stage fit is poor. I show that better first-stage prediction can alleviate this bias. In a two-stage linear regression model with Normal noise, I consider shrinkage in the estimation of the first-stage instrumental variable coefficients. For at least four instrumental variables and a single endogenous regressor, I...
