| Abstract: | The main idea and realization algorithm of the projection pursuit regression based on SMART are introduced.Comparisons of precipitation prediction between PPAR(K) and mean generating function methods are carried out for cities Luzhou and Beibei.The results show that the precision of prediction using PPAR(K) model is much better than that of mean generating function model. |
