Abstract :
Based on the geometric explanation of integral, a new construction method of GM(1,1)psilas background value for non-equidistance sequence is put forward. This method is able to optimize the result of modeling, so the GM(1,1)psilas fitting precision and prediction precision are advanced greatly and the scope of GM(1,1)psilas application is enlarged wildly.
