Abstract:

A comprehensive research on data transformation from the mechanism is given. Then the guidelines for the construction of the transformation are proposed, and a new type of transformation is constructed based on that. A number of properties of the new transformation are also discussed and applied to a GM(1,1) model. It is proved that the new GM(1,1) model is improved by the new transformation, and the efficiency of this method.
