Notice of Retraction: A goal programming model for computation of fuzzy linear regression with least error

Abstract

The paper presents a simple method for computation of fuzzy linear regression with fuzzy output and crisp inputs. The proposed method is based of Goal Programming technique and for estimation upper and lower fuzzy bands, two separated linear programming models are applied. The proposed method is minimized the estimation error between observed and estimated values and has better performance in comparison with previous approaches. The performance of the method is evaluated by applying the considered data in the same example of other methods and the results illustrate decreasing in total error.
