Improved Combination GM(1, 1) Model and its Application in Distortion Inspection
.It is availability to improve GM(1,1) forecasting precision based on the combination of GM(1,1) model and linear regression.But,it is no good to deal with no-saltation points always based on linear regression,and deal with saltation points based on equidistant GM(1,1) model.So,in the paper，it has definite meaning of theory and practice to advance a new GM(1,1) combination model to solve the problem.Finally some examples are given in the paper.
