A Modified Unbiased GM(1,1) Model

摘要：

In this paper a modified Unbiased GM(1,1) model is constructed by producing new data sequence with the method of transforming every datum of raw data sequence into its 2-th root.It is demonstrated that the property of the modified Unbiased GM(1,1) model is superior to Unbiased GM(1,1) model by a numerical experiment comparison.Moreover, the application of the modified model to electric load forecasting is discussed.
