摘要
文章针对自变量的系数和输出因变量是模糊数的模糊线性回归模型,引入模糊数的可能性均值和方差,构建模糊数的可能性均值-方差距离测度。借助于最小一乘法原理,给出了使得可能性均值-方差距离误差达到最小的回归系数估计值的线性规划模型。最后给出实例说明了方法的有效性和可行性。
        Aiming at the fuzzy linear regression model whose coefficient of independent variable and output dependent variable are fuzzy numbers, this paper constructs fuzzy number's possibilistic mean-variance distance measurement. With the aid of the least absolute principle, the paper presents a linear programming model for the estimation of the regression coefficient with the minimum possibilistic mean-variance distance error. Finally the paper uses two examples of symmetric and asymmetric triangular fuzzy numbers to illustrate the effectiveness and feasibility of the proposed method.
