查询词典 weights

The thinking of this method as follows:Firstly,using single evaluation methods to evaluate.If the evaluation results aren\'t same,the Spearman rank correlation coefficient is used to calculate the correlation among the results of single evaluation methods.Based on the results,the traditional combined evaluation methods are used to combine the results of the single evaluation method.If the results of the upper combined methods are not same. Here the combined method evaluation indexes,such as Spearman rank correlation coefficient,correlation degree,the max deviation,average deviation,are used to evaluate the upper four combined evaluation methods.The entropy method is used to calculate the weights,and then get the final evaluation result.

首先，采用单一综合评价方法进行评价，对于不一致的评价结果，通过Spearman等级相关系数验证各单一评价方法间是否具有相关性；(来源：4dbdABbbC论文网www.abclunwen.com)对存在相关性的单一评价方法采用组合评价法对其结果进行组合，若所得评价结果仍不一致，采用Spearman等级相关系数、关联度、最大偏差、平均偏差对组合评价方法的组合效果进行评价，最后运用熵权法对上述组合评价进一步组合得到最终评价结果。
