大学男生人体密度计算模型的优选研究

On Optimization of Calculating Model of the Density of the Male College Students’ Body

以身高、体质量指标和其所派生的指标为自变量,以大学男生人体密度指标为因变量,运用科学的研究方法,建立多种回归模型。应用统计参数对回归模型进行比较分析,优选出大学男生人体密度计算的最优回归模型。体重指数模型预测的值与实际测量值呈无差异性,P>0.95水平。

Taking height, weight and index deriving from them as the independent-variable and the density of male college students physical indicators as the dependent varIable,the authors used the scientific methods to establish the multiple regression model. They applied the statistical regression model parameters on a comparative analysis,and selectied the best regression model for the densting calculation of the male college students. The predicted value of the body mass index models and the actual measurements showed no difference, P〉0.95 level.
