題名: | A new approach on Correlation Evaluation with Fuzzy Data and its Applications in Econometrics | 作者: | 吳柏林 Wu,Berlin Yang,Chih Ching |

Traditionally, we use Pearson`s Correlation Coefficient to measure the correlation between data with real value. However, when the data are composed of fuzzy numbers, it is not feasible to use such a traditional approach to determine the fuzzy correlation coefficient. This study proposes the calculation of fuzzy correlation with of fuzzy data: Interval, triangular and trapezoidal. Empirical studies are used to illustrate the application for evaluating fuzzy correlations. More related practical phenomena can be explained by this appropriate definition of fuzzy correlation. | 關聯: | International Journal of Intelligent Technologies and Applied Statistics, 5(2), 109-120 | 資料類型: | article |
