| Abstract: | The reasons why the error is happened with grey model are analyzed, and the mechanism that causes the error to occur is explained. The methods to improve the description of the accuracy and the error of grey model are given. Two new ways to test the error of grey models are defined and proved. The criteria for the accuracy of grey models are proposed, and the practical meaning of every criterion is discussed. Examples demonstrate that the reasonableness and the practicability of the error test and the criteria of the accuracy given are objective and effective. |
