It is well known that high-leverage observations significantly affect the estimation of parameters. So far, mainly redundancy numbers have been used for the detection of single high-leverage observations or of single redundant observations. In this thesis an objective method for the detection of groups of important and less important (and thus redundant) observations is developed. In addition, the parameters which are mainly affected by these groups of observations are identified. The method proposed in this thesis is based on geometric aspects of adjustment theory and uses the singular value decomposition of the design matrix of an adjustment problem and cluster analysis methods for regression diagnostics. Although the proposed method can ...
