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.", |
