| Abstract: | By analyzing the main error source in the GM(1,1) modeling,the GM(1,1) model taking the compensation for model error was proposed and then,through an example,compared the model(with compensation for error) with the results predicted with conventional models GM(1,1),PGM(1,1) and time varying GM(1,1).The results show that the prediction accuracy with the model GM(1,1) of error compensation is the highest. |
| Keywords: | model error GM (1 1) model penalized least squares deformation prediction |
