Calibrating Gompertz in Reverse: Mortality-adjusted (Biological) Ages around the World
By Moshe A. Milevsky This paper develops a statistical and methodological framework for inverting the Gompertz-Makeham (GM) law of mortality for heterogenous populations in a manner consistent with a compensation law of mortality (CLaM), to formally define a global mortality-adjusted (biological) age.
