The Data Processing Method Based On a Kind of New GM (1, 1) Model

摘要：

Based on the fact that the range suitable for a kind of new GM (1, 1) in paper 3 requires the raw class ratios approximate mutually, this paper proposes a kind of data processing method which uses the function F(x)=-e-x+d to transform the raw class ratios and make them more approximate mutually, focusing on the class ratio series fluctuating violently. Then the simulation and prediction precision will be improved effectively after recuperating.
