Empirical Likelihood-Based Estimation of the Treatment Effect in a Pretest–Posttest Study
前测后测研究中基于经验似然的处理效应估计
The pretest-posttest study design is commonly used in medical and social science research to assess the effect of a treatment or an intervention. Recently, interest has been rising in developing inference procedures that improve efficiency while relaxing assumptions used in the pretest-posttest data analysis, especially when the posttest measurement might be missing. In this article we propose a semiparametric estimation procedure based on empirical likelihood (EL) that…
