Abstract
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.
