Title: A New Forecasting Model Based on the Combination of GM(1,1) Model and Linear Regression
Abstract: Aiming at solving the problem of the aberrant points' presence of the history data in GM(1,1) forecasting model,depending on the grey disaster forecasting theory and using the character of linear regression adapting to the short term forecast,a new combined method was come up with. After using GM(1,1) to forecast the possible aberrant date points in the future,the prediction values of the points were made. And for other normal points,subsection linear regression functions were taken. By having applied the new method to the prediction of the country power consumption in Zhejiang province,it showed that the new method had achieved better forecasting results compared with other forecasting models,making up for some deficiencies in GM(1,1) model and linear regression in certain degree.
