"Many ideas in the analysis of heterogeneous mortality are based on the relationship between individual and observed hazard rates. This connection is established with the help of conditional averaging procedure: The observed risk of death at age x is calculated among those who survive this age. The analogy of this result for bivariate survival model with correlated individual hazards is derived. In the case of correlated frailty model the parametric specification of the mean, variance and correlation coefficient of the bivariate frailty distribution among survivors is obtained. The relationship between local association measure and the characteristics of the bivariate frailty distribution among survivors is established." (SUMMARY IN FRE)

相关个体的生存：异质性分析的一些基本结果的延伸

“分析异质死亡率的许多想法都是基于个体风险率和观察到的风险率之间的关系。这种联系是在条件平均程序的帮助下建立的：在 x 年龄观察到的死亡风险是在这个年龄幸存下来的人中计算出来的。推导出该结果对具有相关个体风险的双变量生存模型的类比。在相关衰弱模型的情况下，获得了幸存者之间双变量衰弱分布的均值、方差和相关系数的参数规范。局部关联测度之间的关系并且确定了幸存者之间双变量虚弱分布的特征。” （免费摘要）
