Mouse blood DNA-methylation age clock built by regression on reduced-representation bisulfite-sequencing CpGs, estimating biological age and shown to be slowed by lifespan-extending interventions such as caloric restriction and dwarfism.
Model weights retain the original authors' terms; the pyaging software license does not relicense them.
