Application of Fuzzy Variable Coefficient Regression Model in Fund Evaluation
摘要
Abstract
Based on the existing CAPM model, fuzzy variable coefficient regression was used, which consider Gaussian fuzzy numbers to expand the application range of the fuzzy regression analysis. And fit model by local nuclear power least squares. On the basis of the real life gives more suitable evaluation index GOF, and establish a fuzzy valuation model which is applicable for fund market. Compared with classic regression model, using the fuzzy variable coefficient regression to estimate the parameters have better application value. The results indicate that the fuzzy variable coefficient re- gression method has good suitability.关键词
