灰色GM(1,1)模型的改进模型在房地产价格指数预测中的应用

Applications of Improved Grey GM(1,1) Model for Real Estate Price Index Forecasting

提出了一种结合非线性回归技术的灰色GM(1,1)模型的改进模型.利用我国的房地产价格指数预测作为研究对象,用以验证所提方法的有效性和准确性.根据实证结果,说明了新的改进模型有效提高了经典灰色模型的预测精度.

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.
