Enzymatic activity in the blood, for an enzyme involved in the
metabolism of carcinogenic substances, among a group of 245 unrelated individuals.
Bechtel et al. (1993) identified a mixture of two skewed distributions
by using maximum-likelihood estimation.
Richardson and Green (1997) used a normal mixture estimated using
reversible jump MCMC to estimate the distribution of the enzymatic activity.
