基于小波变换的逐步线性回归分析预测大坝位移

DAM DISPLACEMENT FORECAST WITH STEPWISE REGRESSION ANALYSIS BASED ON WAVELET TRANSFORM

介绍了小波变换及逐步线性回归分析的方法,并将两种方法融合在一起分析预测大坝位移,与传统的逐步线性回归分析相比较,该方法能提高大坝位移的预测精度。

Wavelet transform algorithm and stepwise regression analysis are introduced, which are brought into preprocessing and analysis for dam displacement data. Compared with the stepwise regression analysis, prediction accuracy of dam displacement can be improved by the application of both algorithms fusion.
