Grey Synthetic Degree of Incidence Entropy and Its Application in Traffic Accidents Analysis

摘要

According to the limitations which are found in the calculation about the important degree of attributes, this paper draws on the idea of grey relational entropy to combine grey relational grade with general information entropy and, by making use of the principle of entropy, to analyze the importance degree of attribute, thus presenting a new data analysis method. Finally, we analyze the traffic accidents in a place of North-east China with it. Grey synthetic degree of incidence entropy in this paper can not only play an important role in traffic accidents analysis, but also can be used in other social science fields.
