This paper investigates the impact on area life tables of the specification of unobserved frailty. Frailty specification may affect both the regression effects of area and individual level covariates, and lead to changes in the value of summary mortality parameters, such as life expectancy. The paper also investigates how frailty affects life tables for specific causes of death, especially lung cancer and heart disease. Implications for choice between different model specifications, both in terms of age dependence and frailty, are discussed. The focus is on registered deaths recorded by age, birthplace and by small area within a borough of Greater London.
本文研究了未观察到的脆弱性的设定对地区生命表的影响。脆弱性设定可能会影响地区和个体层面协变量的回归效应，并导致诸如预期寿命等汇总死亡率参数值的变化。本文还研究了脆弱性如何影响特定死因的生命表，尤其是肺癌和心脏病。讨论了在不同模型设定之间进行选择的影响，包括年龄依赖性和脆弱性方面。重点是大伦敦一个行政区内按年龄、出生地和小区域记录的登记死亡情况。
