基于响应不变法的GM(1,1)模型的动态特性分析

The modeling of GM(1,1) model is to gain difference equation by dispersing albinism differential equation, then estimate model parameters by the difference equation. Because of error by dispersing albinism differential equation, the response of difference equation is changed relative to differential equation. A new GM(1,1) model is given based on response invariant method. And then the analysis of dynamic feature of GM(1,1) model based on response invariant method is given, so as to research its characteristics and suitable object of prophesy.
