| Abstract: | The information entropy theory was introduced into parameter estimation of variogram model，to improve weighting method of weighted polynomial regression using the entropy weight method.An experiment was taken with real deformation monitoring data，considering the influence of both distance and the number of point pairs at the same distance.The experimental results show that the variogram model determined by information entropy weighted regression is more reasonable，and interpolating prediction is more accurate. |
| Keywords: | information entropy variogram weighted regression deformation monitoring cross validation |
