'We are observing the rapid growth of available complex data sets and structures that cannot be satisfactorily reconciled with the rigid and restrictive assumptions of traditional methods in statistics and Data Science. This is due to the existence of unstable, non-linear and complex interdependencies between groups and individuals and their heterogeneity. We develop statistical methods to describe and model these phenomena in the language of statistics. Subsequently, we use these as a basis to develop suitable prediction models and to evaluate their reliability.'
Professor Haupt's research is focused on the development of semi- and nonparametric regression and prediction models. In addition to theoretical research on the statistical properties of the developed methods, empirical work is being carried out on a wide range of applications and projects in economics, business and other disciplines.
