title: [Possibilities and limitations in the use of the biomathematic procedure in variability studies on man].
abstract: In an anthropomorphical variability analysis the quantitative description of deterministric changes of (morphological) growth characteristics plays an important role. Working out this component of general variability and its discrimination from the random component in the measureed values underlying the quantitative analysis can be performed by biomathematical procedures. Three groups of such procedures are presented here in a survey manner. They may be employed at different levels of data processing and for quantitative description resp. mathematical modelling of the biological process in question. There are: Empirical regression, so-called internal regression, and nonlinear regression or approximation. The advantages fo employment biomathematical procedures for evaluating and interpretation of measured values of dynamical processes are sketched for the body height growth of human beings as example. But there are also mentioned limitations of application mathematical methods and procedures in the biological area.
