Nonlinear Error Correction Model and Forecasting Based on Wavelet Neural Networks

The forecasting problem of the nonlinear system is discussed. Using wavelet neural network approach, nonlinear error correction model of nonlinear cointegration system is studied based on the signification of linear and nonlinear cointegration. The modeling method of nonlinear error correction model is proposed. The Shanghai and Shenzhen stock markets are analyzed. The results validate more validity of nonlinear error correction model on the wavelet neural network than linear vector autoregressive model, and forecast validly the nonlinear economy system.
