| Abstract: | In this paper we discussed the method about of set up GM(1,1)forecasttingmodel for vibration series. We thought that using the method least squares solution to findthe await parameter a and u of GM(1,1 ) models, it could improve the fitting precision offorecastting model. End of this put forward the accumulated generating is necessary meth-od that to treatment vibration series. |
| Keywords: | vibration series GM(1 1 ) forecastting mode method least squares solu-tion fitting precision fitting relative variance of mean |
