Karl Clemens Mosler

Karl Clemens Mosler (born July 10, 1947 in Bonn ) is a German statistician and mathematician whose work deals in particular with methods of nonparametric analysis of multivariate data, modeling risk and measuring socio-economic inequality.

Career

Karl Mosler was born in Bonn in 1947 and grew up in a family of lawyers and politicians. His father was the international lawyer Hermann Mosler , his mother Anne Mosler , b. Pipberger . His grandfather Karl Mosler was also a lawyer and president of the regional court in Bonn. His father's sister, the economist Hedwig Daniels , was married to Wilhelm Daniels , Lord Mayor of Bonn, and their son Hans Daniels was also Lord Mayor and a member of the German Bundestag .

Karl Mosler grew up in Heidelberg ; he studied at the University of Heidelberg and the University of Munich , the subjects mathematics , physics and statistics . After graduating with a degree in mathematics (1972) he moved to the Technical University of Munich , where he in 1975 Martin J. Beckmann with a thesis on "Optimal transportation networks" doctorate . He then worked as a research assistant at the University of the Federal Armed Forces (later Helmut Schmidt University ) in Hamburg, where he received his habilitation in 1981 in the field of "Statistics and Operations Research" . The subject of the habilitation thesis was “Decision-making rules for risk: multivariate stochastic dominance”.

Mosler has been Professor of Statistics and Econometrics at the University of Cologne since 1995 , Emeritus since 2014. Before that, he taught from 1985 to 1995 as Professor of Statistics and Quantitative Economics at the Helmut Schmidt University in Hamburg. Mosler held visiting and substitute professorships at the Universities of Kassel , Hamburg and Frankfurt (Oder) , as well as in Italy at the Università di Pavia in Pavia and the Università Bocconi in Milan .

Karl Mosler has been with Susanne Mosler , b. Duden , married. The couple has two daughters.

Act

Karl Mosler's scientific work began with regional studies on location theory. A long-term focus then became the analysis of stochastic orders, these are orders that allow the comparison of probability distributions, also in the multi-dimensional. They have numerous applications in a wide variety of fields of economics and statistics: for example, in decisions on risk, including those with multiple goals or attributes, in the measurement of economic inequality and welfare, and in the comparison of alternative estimation statistics.

In the years from 1994 onwards, Mosler, together with Gleb Koshevoy ( Russian Academy of Sciences ), developed a new type of approach to multidimensional probability distributions, namely the representation of a distribution using its lift zonoid . It enables new approaches to multivariate data analysis as well as the measurement of dependency and disparity of distributions. This theory and its applications were reflected in the 2002 monograph “Multivariate Dispersion, Central Regions and Depth. The Lift Zonoid Approach ”. Data depths and their calculation are still the focus of his research, as well as their application to problems of supervised learning .

Another area of ​​work of Mosler was the diagnosis of mixtures and especially the analysis of unobserved heterogeneity in length of stay models with microdata.

Mosler has published more than 70 scientific articles. He is the author or editor of 14 books, 4 of which are textbooks on mathematics and statistics. Some of his books have appeared in several editions, so that there are a total of 38 book publications. Co-authors of his textbooks are Friedrich Schmid , Rainer Dyckerhoff , Christoph Scheicher from the University of Cologne and Tatjana Lange from the University of Merseburg .

From 1998 to 2004 Mosler acted as editor of the journal "AStA Advances in Statistical Analysis". From 2004 to 2008 he was chairman of the German Statistical Society (DStatG) and has been an honorary member since 2016. Together with Göran Kauermann and Joachim Röhmel , he founded the German Statistics Working Group (DAGStat) in 2005 , the amalgamation of all scientific societies in Germany that deal with statistical methods. From 1987 to 1993 Mosler was a member of the deputation of the Hamburg Authority for Science and Research .
