| Abstract: | In this paper, a time series model, a regression model and a grey forecast model are established respectively based on the data of per capita disposable income of urban households in Anhui province from 1995 to 2009. Then the advantages and disadvantages of each model are integrated to obtain the optimal combination forecasting model by determining the weight coefficient of each single forecase through making the sum of combination forecast error square least. At last, these forecast methods are evaluated, and it is concluded that the combination forecast is more accurate. |
