Description: Provides tools to decompose differences in cohort health expectancy (HE)
    by age and cause using longitudinal data. The package implements a novel
    longitudinal attribution method based on a semiparametric additive hazards
    model with time-dependent covariates, specifically designed to address interval
    censoring and semi-competing risks via a copula framework. The resulting
    age-cause-specific contributions to disability prevalence and death probability
    can be used to quantify and decompose differences in cohort HE between groups.
    The package supports stepwise replacement decomposition algorithms and is
    applicable to cohort-based health disparity research across diverse populations.
