Multi-class and multi-index evaluation based on grey correlation and principal component analysis method and its application

Multi-index evaluation is a main topic in the evaluation domain, especially the selection and the analysis between the indexes of multi-class problem and multi-index evaluation, which is important between theoretical and practical research. Financial Firstly, according to the individuals and the targets in the evaluation, a appropriate evaluation index system with two-level indexes is proposed. Additionally, the principal component analysis method for the second level standardized indexes is used to determine the first level value. Moreover, the grey correlation is employed to analyze the dynamic time series to obtain the key factors. At last, the method is used to the financial investment in Jiangsu Province as an instance of the performance evaluation to verify the validity of the above method.
