| Abstract: | The process of modeling GM(1,1) gray model was introduced in this paper.After being fixed by the method of recursive compensation of identical dimensions,the model could be developed into GM(1,1) model with recursive compensation by grey number of identical dimensions.Then,dynamic forecast of the population of Zhejiang Province in the period 2010 to 2020 was hold by using the newly obtained model.Accurate comparison result shows that the forecasting is more accurate and the result is more reliable. |
