摘要
Based on the characteristic of GM (1,1) nodelling, the paper presents a Zero SettingRegression Method, it has made the short-term prediction of 3-dimension non-negative sequence possible and has the advantages of easier in pretreatment of date, quicker derivation of parameters,accurate estimation, simplification of forecasting model,etc. It is particularly suitable to establishGM (1,1) model group without the help of computer.
