Statistical Diagnostic of Center Fuzzy Linear Regression Model Based on Fuzzy Decentring Degree
Aimed at the center fuzzy linear regression model with real input and fuzzy output, the model parameter estimation is discussed on data deletion of fuzzy decentring degree. Statistical diagnostic quantity is established to test outliers or strong influential points in the observed data. And the step is given to examine with the statistical diagnostic quantity. At last the example suggests that the method can improve the accuracy of the computational results effectively.
