The Correlation and Difference on Fuzzy Sets and its Applications in Medicine

本文在Pal等定义模糊子集相关系数的基础上,定义了模糊子集的差异系数,指出了相关系数与差异系数的联系,从而提出了相关性与差异性的统一判据。最后用一个实际的医学例子说明了进行相关性和差异性检验的数据处理方法。

Based on the correlation coefficient about fuzzy sets defined by Pal, the difference coefficient about fuzzy sets is defined in this paper, and the relationship between the correlation coefficient and the difference coefficient of the fuzzy sets is demonstrated. Furthermore, the unified criteria of the correlation and the difference of fuzzy subsets are suggested. Finally, by means of a practical example in medicine, the methods of processing the data in the test of the correlation and the difference are given in detail.
