摘要
It is our pleasure to have an opportunity of making comments on this fine work in that the authors present a comprehensive review on empirical likelihood(EL)methods for integrative data analyses.This paper focuses on a unified methodological framework based on EL and estimating equations(EE)to sequentially combine summary information from individual data batches to obtain desirable estimation and inference comparable to those obtained by the EL method utilizing all individual-level data.The latter is sometimes referred to as an oracle estimation and inference in the setting of massively distributed data batches.
