From: Thinking outside the curve, part I: modeling birthweight distribution
Competing Models for Birthweight Distribution. (a) A contaminated normal model, a 2-component normal mixture model, and a 4-component normal mixture model are compared. The results are based on a single sample of size 50000 from the population of white singletons born to heavily smoking mothers. (b) to (d) Close-up views of the competing models are displayed.
