对花样游泳运动员选材研究中,所要考察众多影响因素的观测值,有些是定量的,有些是定性的,对这些数据是无法用多元回归分析方法进行分析研究的。运用数量化方法(Ⅰ),能够在充分利用各因素提供的信息基础上,建立一个定性变量和定量变量的混合模型,从而给出便于教练员在实际工作中使用的花样游泳运动员选材的评分标准。数量化方法(Ⅰ)是以建立预报关系为目的,由多元回归分析方法引伸出来的方法,它的计算工作可直接籍助回归分析的标准程序进行,使用非常方便。
In the study of material selection of synchronized swimmers, many observations of influencing factors are to be investigated, some of them are quantitative and some are qualitative. Therefore, the data can not be analyzed by multiple regression analysis. Using quantitative method (I), a mixed model of qualitative variables and quantitative variables can be established by making full use of the information provided by each factor, so as to give the grading standard of the synchronized swimmers for the practical work of the coaches . The method of quantification (Ⅰ) is a method derived from the multiple regression analysis method for the purpose of establishing the forecasting relationship. Its calculation work can be performed directly by the standard procedure of regression analysis, and is very convenient to use.
