di: Deficit Index (DI)
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
