大学女生身体密度回归模型的实证研究

Empirical Study on the Body Density Regression Model of University Female Students

依据浙江树人大学大学女生的身高、体重及其派生指标,运用科学的统计方法建立计算身体密度的一元回归和多元回归模型。运用方差分析对各种回归模型预测值与实际测量值进行比较研究。结果显示,多元回归模型的预测值与实际测量值无差异,P>0.90水平。为完善大学生体质健康评价指标提供一定的理论依据。

On the basis of height, weight and its derivative indexes of the female university students, the use of statistical meth- ods of scientific establishment of a regression and multiple regression model to calculate body density. Research of regression model predicted values are compared with the actual measured value using analysis of variance, so as to choose the best regres- sion. Results show that the multiple regression model for predicting value and the actual measured values showed no differ- ence, P 〉 0.90 level. The aim of the paper is to provide a theoretical basis for the improvement of college students＂ physical health evaluation index.
