通过选用目前在体育评价中常用的三种综合评价方法:RSR法、主成分分析法和加权积分法,对2003-2004NBA现役优秀中锋竞技水平的评价、比较得出:RSR法评价属综合评价,但各指标在综合水平中的地位和作用是均等的,没有分出各指标的重要性;主成分分析法具有高度的数据化和减少变量个数特点,但原始数据需先进行标准化处理且各指标的权重由方差大小来确定,与实际要求不相符合,评价失真;加权积分法评价,通过咨询专家来确定评价指标的权重,再乘以各指标的位置百分法得分,得出综合评分,既有实践经验又有科学评分,是现行三种评价方法中的最优评价方法。
Through the selection of three comprehensive evaluation methods commonly used in sport evaluation at present: RSR method, principal component analysis method and weighted integral method, the evaluation of 2003-2004NBA elite active centers is conducted, and the results show that RSR method is a comprehensive evaluation, However, the status and function of each index in the comprehensive level are equal, and the importance of each index is not separated. The principal component analysis method has a high degree of dataization and reduces the number of variables, but the original data needs to be standardized first and each The weight of the indicator is determined by the size of the variance, which is inconsistent with the actual requirements and the evaluation is distorted. The weighted integral method is used to evaluate the weight of the evaluation index by consulting the experts and multiplied by the percentage of the position of each index to obtain the comprehensive score , Both practical experience and scientific score, is the best of the three evaluation methods in the current evaluation method.
