Title
Covariate balance using empirical likelihood-based methods.

Abstract
The empirical likelihood method is a nonparametric approach that allows
the ef?cient incorporation of side information. We present two applications
of this method for the analysis of data from randomized studies, where we
incorporate the auxiliary information that the treatment groups are
balanced in expectation with respect to the covariates due to the
randomization. We consider the estimation of the difference between the
means of the outcome for the treatment groups and of the Mann-Whitney
measure of association. We report results from simulation studies and
illustrate the new methods using real data. We end by presenting a
covariate balance method for observational studies as an alternative
approach to the propensity score-based methods.
