The height/weight relation of human growth as given in the tables of Maaser (1974) and other authors shows a loosely linear behaviour from the second year up to puberty when plotted in semilogarithmic coordinates (Krüger 1975). Basing on this property mathematical tests are discussed to include the first year of life in the representation of the height/weight relation by adding but one term to the linear equation in the semilogarithmic system. After less successful suggestions a modified form of the exponential function was found to meet requirements relatively well as is shown by the results of nonlinear regressions for male and female following the Paul-method. In a second attempt, the more distinct linear course from about 6 1/2 years on is used as a basis for approximation by adding a function for the difference values against the height/weight tables. Results of the Paul-method are given and compared with the first test.
马泽尔（1974年）及其他作者的表格中给出的人类生长的身高/体重关系表明，当以半对数坐标绘制时（克鲁格，1975年），从第二年到青春期呈现出一种松散的线性关系。基于这一特性，讨论了数学测试方法，以便通过在半对数系统的线性方程中仅增加一项，将生命的第一年纳入身高/体重关系的表示中。在一些不太成功的建议之后，发现指数函数的一种修改形式相对较好地满足了要求，如采用保罗方法对男性和女性进行非线性回归的结果所示。在第二次尝试中，以大约6.5岁之后更明显的线性过程为基础进行近似，方法是添加一个针对身高/体重表差值的函数。给出了保罗方法的结果，并与第一次测试结果进行了比较。
