| Abstract: | In deformation data processing,due to various approximations existing in the process of building model,it is inevitable that the model errors exist in the adjustment system.We discusses some theoretical problems affecting parameters estimation,proposes that model error can be solved with semiparametric penalized least squares and discusses the choice of regular matrix R and smoothing parameter α affecting the forecasted results.Finally,an adjustment problem in dam safety monitoring is used to test the method and the semiparametric model,autoregressive model,grey model and grey wavelet analysis method are compared with each other.The results demostrate that the model errors can be compensated correctly by semiparemetric method. |
| Keywords: | model error semiparametric penalized least squares estimation regular matrix smoothing parameter |
