Abstract In this paper the robustness of Brass's child-survivorship indirect mortality estimation technique is investigated. An analytical method is developed for studying the error or bias caused in indirect mortality estimates by poor data, badly chosen model functions, and specific demographic assumptions that are often violated in practice. The resulting analytical expressions give insight into the rationale of indirect methods, the conditions under which they are robust, and the magnitude of errors that occur when specific assumptions are violated.
本文研究了 Brass 的儿童生存间接死亡率估计技术的稳健性。本文开发了一种分析方法，用于研究因数据质量差、模型函数选择不当以及实践中经常违反的特定人口学假设而导致间接死亡率估计中的误差或偏差。所得的分析表达式深入了解了间接方法的基本原理、稳健性的条件以及特定假设违反时发生的误差幅度。
