| Abstract: | In this paper, the grey model GM(2,1) was corrected. The time response series of GM(1,1) and GM(2,1) were given by means of using the Z transform method. Meanwhile, the grey forecasting models were improved and it was verified that the time response series had the properties of autoregression. |
