| Abstract: | Many of the statis tical techniques and concepts,such as residual analysis,regression diagnostics,in the past analysis etc.,developed in recent quarter century,are used to exhibit if the data fit the assumption of the model we have made,and some times to reach certain significant conclusions in practice.In this paper,we use these techniques to analyses the relation ship between the yield of dryland spring wheat and the precipitation in the Mulci County of Xinjiang.With that the model to predieting yield of wheat is established,by using the method of selecting regression equation. |
