A classification of indices of healthy longevity. Healthy longevity refers to analyses that incorporate mortality and health, and use that information to address questions about length of life. Healthy longevity may focus on life lived in different states of health or life lost due to particular causes of mortality or morbidity. HE = health expectancy. HALE = health adjusted life expectancy. QALY = quality-adjusted life years. DALY = disability-adjusted life years. [1] Analyses routinely report only expected values. [2] In addition to expectations, this method also provides the variance, standard deviation, coefficient of variation, and skewness, as well as higher moments if desired
