【Abstract】 Time series analysis method is a main method by which deformation forecasting model is established in deformation measurements. This paper discusses the problems such as how to determine the model parameters and model rank when AR model is used to establish deformation forecasting model. It is pointed out in this paper that the least squares method and dynamic data system (DDS) is an appropriate method to establish deformation forecasting model when the sample is limited.更多还原
