This article introduces a new method of how to choose suitable class ratio according to the class ratio modeling method thought. It causes class ratio modeling method to be used on the non-steady primitive sequence which has non-homogeneous grey index law directly. It both extends application scope of the class ratio modeling method, and avoids the tedious data pretreatment process effectively while improving prediction precision of model GM (1, 1).
