The method for analysis of the ontogenetic changes of size and shape based on the decomposition of Kullback divergence into parts corresponding to the principal components, found for intragroup variability of signs is suggested. The application of this method is illustrated by the analysis of age changes of body proportions for boys 3-17 years old. Before the pubertal period the stable tendency to a relative lengthening of extremities which changes to a contrast one at age of 12-14 has been pointed out. The definitive differences of proportions to a considerable extent is determined by variability of biological age at the group of children.
提出了一种基于将库尔贝克散度分解为与主成分相对应的部分来分析大小和形状个体发育变化的方法,这些主成分是针对组内特征变异性找到的。通过对3至17岁男孩身体比例的年龄变化分析来说明该方法的应用。已指出在青春期前四肢相对延长的稳定趋势,在12至14岁时变为相反趋势。儿童组中生物学年龄的变异性在很大程度上决定了比例的最终差异。
