Application of Time Series Analysis Combined with Spectral Analysis in Deformation Data Processing
Yang Guo-hu · Journal of Water Resources and Architectural Engineering · 2013
The time series analysis is of a certain precision in data processing and forecast,butit can notdistinguish the seasonal deformation factors hidden in the time series.Here,the spectral analysismethod is introduced into the data preprocessing so as to make the further processing and forecast. The result shows that the combination of the time series analysis and spectral analysis can further improve the accuracy of the deformation processing and forecast.
