Table 1 Ability of health categorization to predict survivorship to the frontier of survival measured by the area under the curve (AUC) statistic. 1905 and 1910 cohorts

From: Stratification in health and survival after age 100: evidence from Danish centenarians

  1. Note: The AUC ranges from 0 to 1; a higher AUC implies a better prediction. Medford et al. (2019) define the frontier of survival as the 95th percentile of the centenarian age-at-death distribution. We included upper percentiles as a robustness check
