| Abstract: | This paper briefly introduces fuzzy regression analysis method, which is applied into water science firstly. Aiming at the correlation between water consumption of rice and air temperature in the duration of rice growing period, this paper builds up a fuzzy regression equation. Comparing the result of this method with general regression method in statistics, we have founded that fuzzy regression model provides more information than general regression model does. Both the predictive result from fuzzy regression model and its generalization value are high. |
