| Abstract: | In the paper,the best-equal-dimension-newly-information Double-difference Gray Model is established,which not only broadens the applied scope of Double-difference Gray Model, but also makes certain the best dimension of equal-dimension-newly-information Double-diference Gray Model which parallels the minimum's absolute vale error of GM whose dimension changes frow 5 to 20. The newly fangled maths software tool Matlab is used to program with the linear time,Shanghai's stock's closing price index every week, forecasting the next one. We found,it is found that can forecasts promptly the extent of the future time series' falling or rising. |
