Analysis of Stability on Scatter Degree Method and the Improvement
摘要
Abstract
We analyze the stability of scatter degree method , which is one of the most popular comprehensive evaluation methods, from two aspects respectively by considering abnormal object and extreme sample using sto -chastic simulation method , and then obtain some relevant conclusions .On this basis, we present an improved method for scatter degree method by fusing factor analyzing approach into it .Through the analyses of the stochas-tic simulation example , we can conclude that this improved method for scatter degree method can weaken the in-terference of outliers to original data .And then, the numerical example illustrates that the improved method can increase the stability of scatter degree method with the consideration of the internal diversity of a same data group.At last, it is pointed that the scatter degree method applies to the questions with fewer independent indi -cators, while its improved method based on factor analysis is more suitable to the questions in hierarchical struc-ture with more attributes and belonging to different categories .关键词
