编制简略寿命表的关键是如何由年龄别死亡率计算死亡概率,其基本公式是: 在这两个公式的基础上,不少学者导出了更为精确的修正公式,其中最著名的是1939年Reed-Merrell与1943年Greville提出的公式,长期以来为各国编制简略寿命表所采用。近年来,我国编制简略寿命表为了简化计算过程,普遍应用上述基本公式。随着计算工具的改进,我国是否需要采用更为精
The key to compiling an abbreviated life table is how to calculate the probability of death from age-specific mortality. The basic formula is: Based on these two formulas, many scholars have derived more accurate correction formulas, the most famous being the 1939 The formula proposed by Reed-Merrell and Greville in 1943 has long been used by countries for the preparation of abbreviated life tables. In recent years, China’s preparation of a simple life table in order to simplify the calculation process, the general application of the above basic formula. With the improvement of computational tools, whether or not our country needs to adopt a more refined approach
