| Abstract:This paper combines the ideas and methods of the hierarchical linear model and the grey theory and gives a new statistical model called accumulated multilevel statistical model.Combined with the fact of the Yangtze River Delta,the annual rainfall forecast model is built.The comparison between predictive value and measured value indicates that the relative error is small and the proposed model is practical.Thus rainfall forecast now has a new means. |
