| Abstract: | In view of the situation that input was exact,and output and the coefficient were the symmetric trapezoidal fuzzy numbers,fuzzy linear regression model was established,its least squares estimation was given and the evaluation method for model performance was proposed.When the input,output and coefficients are all depredated into exact value,the estimation is depredated into the classic least squares estimation. |
