| Abstract: | It is studied in this paper,that how the parameters $a$ and $u$ of grey model GM(1,1) worked up are affected by every datum of original series minus same constant $2β$, and which value of constant $β$ is found out so that the grey model is optimal in the sense of optimum fitting line. |
