# dnamfitage
Sex-specific Klemera–Doubal biological-age composite that calculates DNAm gait speed, grip strength, VO2max, and original DNAmGrimAge internally from methylation, age, and female inputs.
Model weights retain the original authors' terms; the pyaging software license does not relicense them.
