Optimization For a Kind of Quasi-index Sequence Model

摘要：

Basing on the traditional GM(1,1) model and combining the least square method principle, this article present a improved method which directly builds a model with quasi-index rule original sequence , and a suitable optimization in background value of the new model is also mentioned..The present method can overcome the blindness character of the tradition GM(1,1) model, and it can inevitably enhance the accuracy of fitting and prediction.
