Mean Shift versus Variance Inflation Approach for Outlier Detection—A Comparative Study

Autor: Rüdiger Lehmann, Michael Lösler, Frank Neitzel

Publikováno v: Mathematics, Vol 8, Iss 6, p 991 (2020)

Outlier detection is one of the most important tasks in the analysis of measured quantities to ensure reliable results. In recent years, a variety of multi-sensor platforms has become available, which allow autonomous and continuous acquisition of la

Publikováno v: Applied Geomatics. 15:77-95

The operator-software impact describes the differences between results introduced by different operators using identical software packages but applying different analysis strategies to the same data. This contribution studies the operator-software im

Bias in least-squares adjustment of implicit functional models

Autor: Frank Neitzel, Michael Lösler, Cornelia Eschelbach, Rüdiger Lehmann

Publikováno v: Survey Review. 53:223-234

To evaluate the benefit of a measurement procedure onto the estimated parameters, the dispersion of the parameters is usually used. To draw objective conclusions, unbiased or at least almost unbias...
