题目：Bayesian jackknife empirical likelihood with complex surveys

摘要：This work focuses on the application of the Bayesian jackknife empirical likelihood method to survey data with general unequal probability sampling designs. We examine the parameters characterized by U-statistics and establish the asymptotic distribution of the Bayesian jackknife pseudo-empirical likelihood ratio statistic with a non-informative prior. We also investigate the impact of auxiliary information, as well as the use of design weights or calibration weights. Some numerical analysis evaluates the effectiveness of the Bayesian jackknife pseudo-empirical likelihood ratio confidence intervals. Our results show that the proposed method exhibits superior performance compared to approaches relying on the jackknife pseudo-empirical likelihood, effectively addressing its limitations.
