Abstract:
A model for the physical growth of individual children from birth to adulthood is proposed which is linear in the model parameters. The advantages of linear over nonlinear models include the relative ease and costs of fitting the model to data of individuals and the fact that statistical methods are more readily available for analysis of parameters from linear models than for nonlinear models. The proposed linear model and the non-linear triple logistic model are both fit to the measured lengths of two boys and two girl followed from birth to 18 years of age.
