     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.
