Abstract


Mortality measures, such as remaining life expectancy, the modal age at death, life disparity, the lifetable entropy, and the Gini coefficient are conventionally computed from life tables incorporating assumptions about the distribution of deaths in each age interval. An alternative approach is to fit a continuous model and derive expressions for the corresponding conventional mortality measures. This study argues that model-based mortality measures might be useful as they are less sensitive to censoring, as well as points out the cases when life-table and model-based measures differ substantially.
