| Abstract: | An improved grey GM(1,1) model using a technique of nonlinear regression is proposed.We use real estate price index forecasting of China as our case study to test the efficiency and accuracy of the proposed method.According to the experimental results,our proposed new method obviously can improve the prediction accuracy of the original grey model. |
