Grey Incidence Analysis Based on Coefficient of Determination and Its Economic Application with the Data of Central Henan Urban Agglomeration
Grey incidence analysis is the basis of grey model, grey decision and grey control and concentrates on the degree of grey incidence. Grey incidence analysis compares geometric patterns of system statistical series to analyze the degree of grey incidence of the system factors. The more similar the curves are, the closer the developmental trend of each factor, then the greater the degree of grey incidence. This paper constructs a new model of calculating the degree of grey incidence on the base of this fundamental idea. First, this paper deals with the original sequence by accumulating generation and specific gravity generation. Then, with the principle of the coefficient of determination, it undertakes two ways to calculate the degree of grey incidence. At last, we use the data of Central Henan Urban Agglomeration to show the method is practical and reliable.
