Weighted Geometric Means Combination Foecast Model and Its Application
Fengxiao Wang · Journal of Kashgar Teachers College · 2013
Weighted geometric means combination forecast is a kind of nonlinear combination Forecasting model.Based on Theil coefficient,the improved weighted geometric means comdination forecasting model is proposed.Its properties are discussed.On basis of concepts such as superior combination forseasting and dominant forecasting method etc,the existence of non-inferior combination forecast,superior combination forecasting and redundant forecasting method are studied.Redundant information is given in the determining theorem,Application example shows that this nonlinear model is effective.
