Title: Multi-variable grey model forecast based on factors synthetic integration
Abstract: Social economic system is a multi-level,nonlinear complex system affected by many factors with grey characteristics.Existing statistical data are few and incomplete,which makes grey method apply widely.On the basis of grey incidence,we integrate the factors with the same correlation level into a factor with no dimension,and take grey incidence value as weight coefficient by normalizing to generate sequence data,and set up multi-variable forecasting model.In this way the method facilitates the choice of grey factors.Meanwhile,the integration model invites sound forecasting results in terms of accuracy and fitness.
