Profiling Compliers in Instrumental Variables Designs
Dominik Hangartner, Moritz Marbach, Leonard Henckel +3
Instrumental variable (IV) analyses are becoming common in health services research and epidemiology. IV analyses can be used both to analyze randomized trials with noncompliance a…
Hospital Quality Risk Standardization via Approximate Balancing Weights
Luke Keele, Eli Ben-Michael, Avi Feller +2
Comparing outcomes across hospitals, often to identify underperforming hospitals, is a critical task in health services research. However, naive comparisons of average outcomes, su…
Protocol for a Study of the Effect of Surface Mining in Central Appalachia on Adverse Birth Outcomes
Dylan S. Small, Dan Firth, Luke Keele +4
Surface mining has become a major method of coal mining in Central Appalachia alongside the traditional underground mining. Concerns have been raised about the health effects of th…
Comparing the Performance of Statistical Adjustment Methods By Recovering the Experimental Benchmark from the REFLUX Trial
Luke Keele, Stephen O'Neill, Richard Grieve
Much evidence in comparative effectiveness research is based on observational studies. Researchers who conduct observational studies typically assume that there are no unobservable…
Biased Encouragements and Heterogeneous Effects in an Instrumental Variable Study of Emergency General Surgical Outcomes
Colin B. Fogarty, Kwonsang Lee, Rachel R. Kelz +1
We investigate the efficacy of surgical versus non-surgical management for two gastrointestinal conditions, colitis and diverticulitis, using observational data. We deploy an instr…
Evaluating A Key Instrumental Variable Assumption Using Randomization Tests
Zach Branson, Luke Keele
Instrumental variable (IV) analyses are becoming common in health services research and epidemiology. Most IV analyses use naturally occurring instruments, such as distance to a ho…
