Two Stage and Related Estimators and Their Applications
统一处理两阶段估计量的性质，给出一致性、有效性和正确推断的一般条件，并应用于含预期和诊断检验的模型，简化现有结果并推导新结论。
This paper aims to provide a unified treatment of the properties of two stage estimators. General conditions are set forth for consistency, efficiency and correct inferences. Applications of the general theorems are made to models with expectations and diagnostic tests. The general approach frequently enables much simpler derivation of existing results, and provides a number of new ones.
