摘要
针对输入为精确、输出和系数为对称梯形模糊数的情况,建立模糊线性回归模型,给出该模型的最小二乘估计和模型性能的评价方法.当输入、输出以及系数都退化为精确值时,该估计退化为经典的最小二乘估计.
In view of the situation that input was exact, and output and the coefficient were the symmetric trapezoidal fuzzy numbers, fuzzy linear regression model was established, its least squares estimation was given and the evaluation method for model performance was proposed. When the input, output and coefficients are all depredated into exact value, the estimation is depredated into the classic least squares estimation.
