Research on properties of superior combined forecasting models based on correlation coefficients
Huayou Chen · Journal of systems engineering · 2006
The traditional combined forecasting models are constructed by improving certain fitting errors.The combined forecasting model based on correlation coefficients is different from traditional one,which is a new idea to study combined forecasting methods.Some new concepts are put forward in this paper,such as superior combined forecasting,dominant forecasting method,redundant degree etc.Then some basic problems are discussed that are existence of noninferior combination forecasting,superior combination forecasting and redundant forecasting method.Finally a judgement theorem of redundant forecasting method is proved,which shows theoretically that this model is effective.This conclusion is checked by an illustrated numerical example.
