kdmage

Klemera-Doubal biological age, trained sex-specifically on NHANES III adults aged 30-75 who were not pregnant, using the BioAge package defaults. Biomarker parameters were fit on SI-unit variants so they are natively in pyaging's unit convention, and C-reactive protein is supplied raw in mg/dL and log1p-transformed inside the clock. Sex is coded female = 1 and male = 0; a dataset with no female column scores every sample with the male parameters.
