Research on Screening Methods of Single Forecast Model for Combination Forecast Modeling

Combination forecast modeling is essentially a process that select and make use of the information gained through single forecast model. This paper analyses how to make judgment about the conditions that the single forecast models should meet. Moreover, this paper applies the co-integration theory to model screening, and thus puts forward the comprehensive methods and steps for single forecast model screening for combination forecast modeling in three aspects in order to improve forecast precision and simplify computation.
