| Abstract: | This paper describes the basic principles of stepwise regression. And the parer establishes, tests and analyses five stepwise regression models by data from 1991 to 2007, which can express the demand regularities of five fruits. At last, the five models are used to forecast demands for fruits from 2008 to 2012. |
