Functional Concurrent Regression with Compositional Covariates to Study the Time-Varying Effect of Causes of Death on Human Longevity

We study the relationship over time between causes of death and longevity.
Specifically, we investigate whether variations in cause-specific mortality rates can be predictive of life expectancy at birth, considering three compositions of causes of death related to three age classes, namely 0–4, 40–64 and 65+. Employing tools from functional and compositional data analysis, we propose a novel functional concurrent regression model with compositional covariates. A penalized estimation procedure for estimating the regression coefficients and for selecting variables is developed. The results confirm the important role of neoplasms and cardiovascular diseases emerged in other studies and reveal other contributions not observed yet.
