MGM(1,n) based on adaptive regression of residual

In view of the face that with the forecast of MGM(1,n),the gap between simulation and prediction residual of different variables is big,adaptive regression model was introduced to the residual estimates of different variables in the paper.The overall residual became smoothing,so the rising trend of residuals was restrained.The simulation results showed that the forecast accuracy of residual adaptive regression MGM(1,n) was improved significantly.
