| Abstract: | The GM(1,1) model is generally founded on the position information when it is used in local crustal deformation prediction.However,it can not fully reflect the change of points.Therefore the GM(1,1) model based on buffer operator is proposed.The position sequence of crustal deformation is pre-adjusted by buffer operator according to the qualitative analysis of the velocity information before forecasting.By using the real data processing as an example,it is revealed that the prediction accuracy is greatly im... |
