Sam Pimentel, of the Department of Statistics at the University of California, Berkeley, will present: "Optimal Tradeoffs in Matched Designs Comparing US-trained and Internationally-trained Surgeons" Abstract: Does receiving a medical education outside the United States impact a surgeon's performance? We study this question by matching operations performed by internationally-trained surgeons to those performed by US-trained surgeons in reanalysis of a large health outcomes study. An effective matched design must achieve several goals, including balancing covariate distributions marginally, ensuring units within…
