【Abstract】 In the basis of the grade difference format, MGM p (1, n ) model is proposed and some precision grade difference formats are obtained. The error will be interjecting to them. In the cases of comparative error, the gray model, which is a new gray GMG p (1, n ) model, is expound and discussed. The models have nice anti-interference; the example manifest that the model has good effect.更多还原
