时变参数模型 meaning in English

time-varying parameter model

The paper consists of several parts as following : firstly , we probe an estimating method with the time - change parameters to overcome the problem with greater errors that us think a dynamical process with the time - change parameters as a static process with the no time - change parameters and forecast the time - change parameters system by the model with the no time - change parameters
本文主要进行了以下几方面的工作： 1探讨了一种动态系统的时变参数的估计方法，克服了以往把一个时变参数的动态过程当作了非时变参数的静态过程，而用非时变参数模型预报时变参数系统的状态时带来的较大误差问题。
