Evaluating the Balance of Observed Covariates
摘要
Several recent articles by Brumberg et al. (Biometrics 80(3) 2024), Hansen and Bowers (Stat Sci 23:219–236, 2008), Pimentel et al. (J Am Stat Assoc 110(510):515–527, 2015), and Yu (Biometrics 77(4)L1276–1288, 2021) have suggested comparing the covariate balance in a pair-matched or 1-to-K matched sample to the covariate balance in simulated completely randomized experiments built from the same covariate data. This technique is illustrated and discussed.
