Linear Combination Forecasting Model and its Application
线性组合预测模型及其应用

The key of forecasting is modeling,but every kind of model has its own advantages.A more efficient model can be obtained by a linear combination of some models.In this paper,Fujian urban household's Engle coefficient is forecasted by linear regression model,gray system model,genetic algorithms back propagation network (GABP) model and linear combination model.It is found that the best one is the linear combination model.
