摘要
在综合考虑数学模型的预测精度与编程实现的可操作性基础上,提出了利用模块对变形监测数据进行时间序列分析,并概括介绍了该模块的3个主要命令使用方法,解决了时间序列分析在监测数据处理中实现起来非常繁琐的问题。最后通过与环境下动态灰色模型综合比较,证明了时间序列分析在变形监测数据处理中操作简单,模拟精度和预测精度都较高。
Considering the forecasting precision of the mathematic model and the feasibility to program synthetically, the SAS/ETS module is used to analyze deformation surveying data, and the use method of three major commands are introduced. The applied problem of the time sequence analysis is solved, It proves that the SAS/ ETS module is very easy to use, the precision of simulating and forecasting is high in the processing of deformation monitoring data by comparing with the gray model.
