A SIMPLE METHOD FOR EVALUATION OF FUZZY LINEAR REGRESSION MODELS BY ORDINARY LEAST- SQUARES METHOD

In this study, we have introduced a simple method for eveluation of fuuzy regression model. The method is a modification of Kim and Bishus method appeared in fuzzy Sets and Systems 100 (1998) 343-352 in wich, they tried to close the membership function of observed and estimated responses, but their method sometimes dose not product acceptable coefficients for fuzzy linear regression model.
