=== Role of Chronological Age ===
The role of Chronological Age (CA) in the estimation of Biological Age (BA) varies significantly between different methods. In MLR and PCA, CA is used as a criterion for selecting biomarkers. This means that the biomarkers are chosen based on how well they correlate with CA. In this context, CA is not an independent variable in the statistical model but rather a reference point against which the predictive power of biomarkers is measured.
In contrast, Hochschild’s method and KDM treat CA as an independent variable. This means CA is directly incorporated into the model as one of the variables that predict BA.

====Comparison and Discussion====
While MLR and PCA treat CA as a criterion for biomarker selection, Hochschild’s method and KDM consider CA as an independent variable. The choice of method depends on the specific research goals and the nature of the available data. MLR and PCA are more straightforward and are often used in initial studies, while Hochschild’s method and KDM provide a more nuanced view of the aging process.
