The Grey Model Based on Class Ratio Modeling

This paper has compared the raw series with its class ratio sequences in the class ratio dispersion and come to the conclusion that the class ratio sequence has the better degree of smoothness. For the big modeling error to the high growth sequence, we propose a new method that simulates the class ratio sequences firstly by the grey model and then returns to the raw series. Some examples show that the new method has better effect on the low growth sequence, the sequence which has high developing coefficient but steady class ratio, and the rapid and vigorous growth sequence which has fierce class ratio.
