摘要
According to some problems in the grey incidence for panel data, the panel data initialization method is put forward firstly. Using the grid method, we describe the geometric characteristics of the panel data in three dimensions, and split the grid into line. Then based on the slope of the line in space, a grid incidence coefficient is constructed. Through the arithmetic average, we obtain grey grid incidence model, and discuss the nature of this model. Lastly an example verifies the feasibility and effectiveness of this method, and the results show that grey grid incidence model has good effects.
