Description: A set of utilities for calculating the Deficit (frailty)
        Index (DI) in gerontological studies. The deficit index was
        first proposed by Arnold Mitnitski and Kenneth Rockwood and
        represents a proxy measure of aging and also can be served as a
        sensitive predictor of survival. For more information, see
        (i)"Accumulation of Deficits as a Proxy Measure of Aging" by
        Arnold B. Mitnitski et al. (2001), The Scientific World Journal
        1, <DOI:10.1100/tsw.2001.58>; (ii) "Frailty, fitness and
        late-life mortality in relation to chronological and biological
