Mixture Modeling Results and Mortality for White Singleton Infants. (a) A 4-component normal mixture model, with parameters estimated by combining the results for 25 samples of size 50,000 from the population of white singletons in general, is shown. (b) Estimated birthweight specific-mortality curves are presented for each component of a 4-component normal mixture model, along with confidence bounds determined by Equations (6) and (7) with C 0 = 4.0 and φ = .0055 based on 25 samples of size 50,000 from the population of white singletons in general.
