| Abstract: | Based on sales price indices of houses from 1st quarter in 1998 to 4th quarter in 2008,the ARIMA(p,d,q) mathematical model for time series is designed,which is applied by SAS software; meanwhile,we forecasted the sales price indices of houses from 1st to 4th quarter in 2009; finally,the effectiveness of this module is verified by comparing the forecasted and genuine data. |
