Abstract
Being different from the typical direct modeling method and optimizing methods of background value, we use trapezoid formula and central difference quotient methods to whiten grey derivative and propose a grey modeling method for non-equidistant sequence based on the criteria of the minimum square error sum. The results show that the new model´s fitting precision and prediction precision is improved.
