摘要
利用百分位数法为所选指标制定评分标准 ,并在此基础上利用逐步回归分析的方法建立体质综合评价的数学模型 ,对军人体质综合评价方法进行了探索。在各项指标贡献率的确定上 ,采用的是经逐步回归分析得来的“标准化偏回归系数”与“简单相关系数”的乘积。在对每一个样本各项选中指标进行评分之后 ,进行逐步回归分析 ,建立了体质总体、身体形态、身体机能、身体素质、有氧耐力和力量素质共 6种体质评价的数学模型。这些模型的建立以及评价标准的制定为计算机评价系统的实现提供了基本算法 ,也为《中国军人体质评价系统软件》
This research established evaluation standards for the selected indices by the method of position in hundred score, formed mathematical models by the method of Liner Stepwise Regression, gained standard bias regresion coefficient(abbreviated as 'bi'') and simple correlation similarity coefficient(abbreviated as 'ri',). The product of 'ri'and 'bi'' was contributive rate of each index, then the weight coefficient(abbreviated as 'wi') of each index was defined according to the contrbutive rate. This paper built six kinds of mathematical models which included model of body shape,model of body function,model of sports quality and model of total constitution. These models supplied basic caculation method for computer software, and it made realization of computer systematic software possible.
