|Project Title||Effects of Adjusting for Instrumental Variables on Bias and Precision of Effect Estimates|
Wednesday, June 8, 2011
The authors present results from two simulation studies to provide insight into the problem of conditioning on potential IVs in routine epidemiologic practice. The simulations explored the effects of conditioning on IVs, near IVs (predictors of exposure that are weakly associated with outcome), and confounders on the bias and variance of a binary exposure effect estimate.
