Estimating Attributable Life Expectancy Under the Proportional Mean Residual Life Model.

ABSTRACT: In population-based health research, the so-called population attributable fraction is an important quantity that calculates the percentage of excess risk of morbidity and mortality associated with modifiable risk factors for a given population. While the concept of "risk" is usually measured by event probabilities, in practice it may be of a more direct interest to know the excess life expectancy associated with the modifiable risk factors instead, particularly when mortality is of the ultimate concern. In this paper, we thus propose to study a novel quantity, termed "attributable life expectancy," to measure the population attributable fraction of life expectancy. We further develop a model-based approach for the attributable life expectancy under the Oakes-Dasu proportional mean residua
