Mortality by education level at late-adult ages in Turin: a survival analysis using frailty models with period and cohort approaches

摘要

ObjectivesNeglecting the presence of unobserved heterogeneity in survival analysis models has been showed to potentially lead to underestimating the effect of the covariates included in the analysis. This study aimed to investigate the role of unobserved heterogeneity of frailty on the estimation of mortality differentials from age 50 on by education level.
