- Title
Modeling Dam Deformation Using Varying Coefficient Regression.
- Authors
LU Jun; DAI Wujiao; ZHANG Zhetao
- Abstract
Regression analysis is often used in deformation analysis modeling, however, it is a static model. When the structure or physical properties of the monitoring object change, the static model will no longer be applicable. However, a varying coefficient regression model is a dynamic model and has greater flexibility and adaptability. So varying coefficient regression is introduced into dam deformation analysis. Local linear estimation is used to fit the varying coefficients. Both a simulation experiment and a real dam deformation monitoring data experiment show that a dam deformation model using varying coefficient regression is better than that using ordinary linear regression; and more precise when predicting deformation.
