mccartneyalcohol

Whole-blood DNAm LASSO score trained on log(alcohol units per week + 1), residualized for age, sex and ten genetic principal components. The returned linear score remains on that adjusted natural-log scale; it is not an absolute exposure in physical units. Evaluated out of sample in LBC1936.

Model weights retain the original authors' terms; the pyaging software license does not relicense them.
