The robustness of the product life table estimator of the survival function was studied for large populations under perturbations in the age distribution, changing levels of mortality and changing patterns of fertility. A macrosimulation system, based on a class of stochastic population models called generalised age-dependent branching processes, was used to carry out the numerical investigations. Aside from drastic perturbations in the age distribution and changes in levels of mortality, the product life table estimator of the survival function was found to be robust in large populations, under a variety of conditions.
针对年龄分布受到扰动、死亡率水平变化以及生育模式变化的大群体，研究了生存函数的产品寿命表估计量的稳健性。基于一类称为广义年龄依赖分支过程的随机人口模型的宏观模拟系统，用于进行数值研究。除了年龄分布的剧烈扰动和死亡率水平的变化外，发现在各种条件下，大群体中生存函数的产品寿命表估计量是稳健的。
