The structure of variation in human mortality patterns is explored using a five-parameter competing hazards model and standard multivariate taxonomic procedures. The data consist of 281 national life tables representing a wide range of environmental and cultural regions of the world. A general or average age pattern of mortality was generated for the entire sample using multiple regression procedures. A K mean cluster analysis conducted on the residuals of the regression analysis identified seven distinct models of mortality that differ in characteristic ways from the general pattern. Four of the seven clusters have age patterns of mortality similar to the north, east, south, and west regions of the Coale and Demeny model life tables. The remaining three clusters represent regions of the world and age patterns of mortality that are not represented in the Coale and Demeny model life tables.
利用五参数竞争风险模型和标准多元分类程序，对人类死亡率模式的变化结构进行了探索。数据由281个国家生命表组成，代表了世界上广泛的环境和文化区域。使用多元回归程序为整个样本生成了一般或平均年龄死亡率模式。对回归分析的残差进行的K均值聚类分析确定了七种不同的死亡率模型，它们在特征上与一般模式不同。七个聚类中的四个具有与科尔和德梅尼模型生命表的北部、东部、南部和西部地区相似的年龄死亡率模式。其余三个聚类代表了世界上科尔和德梅尼模型生命表中未体现的区域以及年龄死亡率模式。
