| Abstract: | The initial values of the grey lorecasting model isdiscussed in this paper Based on analysing model-building mechanism of the system and minimizing the quadrati sum of its fitting error, this paper proposes a new method for initiating values, by means o which initial values are more rational and fitting acuracy as well as predicating acuracy o the GM(1.1) model imoroved. |
