Abstract :
We used both linear regression models (RM) and grey model (GM) to predict the gross domestic product (GDP) of Shaanxi province for last few years. Then we proposed a new combination grey model (CGM) based on RM and GM to predict GDP of Shaanxi province again. The simulation results from CGM are much more precise than those from simple models (RM and GM). The whole calculation process can be conducted by MATLAB computer software.
