Zusammenfassung
The biological age is an indicator of the functional conditionof an individual’s body. Unlike the chronological age, which just measures the time from birth, the biological age of a human is also affectedby its medical condition, life habits, some sociodemographic variables, aswell as biomarkers. Taking advantage of the statistical concept of depth,which serves as a measurement of the degree of centrality of a multivariate observation with respect to a dataset, we assess the biological ageof an individual as the chronological age that would make her selectedrecords as deep as possible when compared with those of other individuals with a chronological age similar to hers. Some direct conclusions ofthis imputation technique are presented.
