Robust Estimation Through Estimating Equations
利用估计方程理论，定义了参数定义函数和有效参数，并提供了从一组稳健参数中选择最有效或最易估计的参数的方法。
Utilizing the theory of estimating equations (Godambe, 1960; Godambe & Thompson, 1978), this paper develops concepts of parameter defining function and effective parameter. The paper provides theory and techniques for choosing from a given set of robust parameters one that is most effective, or one that can most efficiently be estimated.
