摘要

For the actual cases of various forecasting problems, combining forecasting models may take different forms. But their forecasting efficiencies may be different for the different models. This paper presents a new kind of combing forecasting model based on the generalized weighted exponential mean and gives two kinds of parameter estimation methods of its weighting coefficients. In finial, the efficiencies of the two kinds of parameter estimation methods are demonstrated by an example. And a very helpful conclusion is obtained, which can lay solid foundations for correct application of the above methods.
