| Abstract: | This paper deals with the robustness and efficiency of surveying data processingfrom the point of view of efficiently using information available and relationship betweenthem. The essential difference between the robust estimation and classical estimation has beendescribed. It also presents the principal criterion for robustizing the data adjustment and com-parison between ressistance and efficiency with several examples. |
