The Design of Weight Function for Robust Estimation Depending on Equivalent Analysis Method

YAO Yi-bin (Wuhan Technical University of Surveying and Mapping, Wuhan 430079, China)  
If we add outliers to observations, the influence of outliers can be equal to change weight. The adjustment result by using robust estimation to process the observations including outliers will be accorded with the result by RLS. Depending on such theory, we recur to the indirect adjustment model and ALS theory to discuss the design of weight function for robust estimation depending on equivalent analysis method.
