| Abstract: | Expressions are given to describe the closeness between the estimated value and observed value for two asymmetric exponential fuzzy numbers.Based on that,the model is given to solve the question of fuzzy multivariable regression with fuzzy input,fuzzy output and crisp coefficients.Finally,using this model,the prediction of field mouse occurrence rate have been done and satisfied result is obtained. |
