摘要
在医院综合效益评价中,独立性权数是反映某些指标间重复信息量大小的一个重要指标。本文用偏相关系数计算方法,通过归一化处理等得到一组独立性权数。同时,也对指标间的负相关、相关系数的选择等问题进行了探讨。
Weight of independence is an index which could be used to indicate the information overlapped between the evaluating variables in the comprehensive benefit evaluation of hospital. In this paper the partial correlation coefficients may be used to calculate the weight of independence. At the same time some problems, such as negative correlation, selection of correlation coefficient, are discussed also.
