Applications of Improved GM(1,1) Model for Real Estate Price in Guangzhou Forecasting

摘要：

An improved grey GM(1,1) model which is based on curve-fitting will be compared with classic grey GM (1,1) model. We use Real Estate Price in Guangzhou from September 2010 to August 2011 as our case to test the availability of non-linear grey GM(1,1) model. The result show that the error of logarithmic grey GM(1, 1) model is less than other models, so it is more effective than classic grey GM(1,1) model to forecast Real Estate Price in Guangzhou.
