Abstract

First, the conditions for GM(1,1) modeling are analyzed, and it revealed that the whole trend of the class ratio sequence and the whole concave‐convex of data sequence both affect the precision of the model. Secondly, the action of translation transformation on the features of data sequence is studied theoretically, and the satisfied interval of translation values is derived. Finally, an effective numerical method is presented which is illustrated by a medical example.
