A New Method for Grey Interval Forecasting

Song Zhongmin (Department of automatic, Huazhong University of Science and technology,Wuhan 430074)  
Being aimed at a kind of series that the discrete degree is large and the whole tendency is increasing, a new method for grey interval forecasting has given by the grey system theory in this paper. the method firstly calculates the class ratio of series, chooses some clique values for class ratio and divides original dates into groups by different clique value, then, establishes non equigap GM(1,1) model for different group and searches forecasting area of original dates by the solution of model.
