Several Important Problems in Time Series Modelling of Deformation Measurement Datum
Wang Teng-jun · Journal of Earth Sciences and Environment · 2008
According to the real problems that are encountered in setting the time series model,this paper studies such problems as the issues of deformation datum pre-proposing,model selecting,model setting and dynamic system stability judging.The methods to calculate the trend datum,periodical datum of deformation are put forward,and the C-programs of ARMA model to analyze the real problem is developed.Comparison between the surveying datum and calculated ones shows the correctness and availability of time series analysis in the data analysis of deformation survey.
