Ledermann formula

Le·der·mann for·mu·la

(lā'dĕr-mahn),
a formula to calculate alcohol dependancy levels. Ledermann showed empirically that the distribution of alcohol consumption in a population is log normal; the formula used this observation to estimate the prevalence of various degrees of alcohol dependency. Some questions have been raised about the validity of Ledermann observations.
