Index of Shanghai Stock Exchange Prediction Based on Regression Model with LR-Type Fuzzy Output
Abstract:We constructed a fuzzy general quadric regression model to deal with the interval financial data based on the fuzzy symmetric quadratic form regression model with crisp inputs and fuzzy outputs, and by taking into account the fuzzy least square method to estimate the unknown parameter in the model.The evaluation standard SAME and SMSE were employed to evaluate and compare the fitting results of the models .Furthemore ,we deduced the data of index of shanghai stock exchange for forecasting the models.Empirical analysis shows the first one is more effective.
