title: [Kunze-Murken growth-specific approximations of somatograms].
abstract: Tables for human height at age values by Kunze and Murken are submitted to mathematical approximations applying the 2-step-model introduced by Sager (1981). The basic term reflects growth as expected when a growth spurt is lacking which may be the case for children with chromosomal aberrations. The 2nd term comprises an expression for the growth spurt proper thus allowing an evaluation for the intensity of the spurt. The approximations as gained with nonlinear regressions show very close agreement with the measurements. Besides the growth curve its first derivative--the growth velocity or increase--is calculated and represented graphically. Moreover the results and their relative amounts against the final values at adulthood are compared for nine height at age tables treated hitherto with the same growth model.
