【Abstract】 This paper investigates a class of linear regression forecasting problems for fuzzy time series,and gives a least\|square regression model for fuzzy data by using the distance in fuzzy number space.It is proved that the model has a unique solution and gives formulae for calculating model parameters and testing the fitting degree of the regression model更多还原
