mammalian2
Universal pan-mammalian clock 2 fits relative age (age divided by species maximum lifespan) and the author inverse transformation returns species-adjusted chronological age in years.
Model weights retain the original authors' terms; the pyaging software license does not relicense them.
| Predicts | chronological age |
| Species | multiple species |
| Tissue | multi-tissue |
| Data type | DNA methylation |
| Model type | elastic net regression |
