Adjuvant-induced alterations of cuticular waxes and their consequences for mechanisms of drought stress resistance
(2023-07-26)The most important function of the cuticular waxes is the shielding of the plant from uncontrolled water loss as well as from pathogens, UV radiation and pollutants. Penetrating agrochemicals are also effectively shielded ... -
Advanced polygenic prediction models via statistical boosting
(2025-03-06)In times of growing availability of large biobanks with extensive genetic data, polygenic prediction modeling has gained importance and aims at capturing an individual's genetic predisposition to specific, often complex, ... -
Ansätze zur Verbesserung der hausärztlichen Versorgung von Menschen mit Migrationshintergrund mit Fokus auf die Demenzdiagnostik
(2021-05-20)People with a migration background represent more than a quarter of the German population and are increasingly at risk of suffering from dementia due to demographic change. Diagnosing dementia depends on language skills, ... -
Bayesian Adaptive Markov Chain Monte Carlo Estimation of Genetic Parameters
(2012-04-18)Accurate estimation of genetic parameters is crucial for an efficient genetic evaluation system. REML and Bayesian methods are commonly used for the estimation of genetic parameters. In Bayesian approach, the idea is to ... -
Challenges and opportunities of using ecological and remote sensing variables for crop pest and disease mapping
(2019-07-15)Crop pest and diseases are responsible for major economic losses in the agricultural systems in Africa resulting in food insecurity. Potential yield losses for major crops across Africa are mainly caused by pests and ... -
Conceptualising and estimating rationalised agricultural optimisation models
(2018-07-19)Computational modelling for quantitative agricultural policy assessment in the EU employs more farm level oriented approaches in recent years. This follows policy instruments that increasingly target the farm level and ... -
A Contribution to Functional Data Analysis
(2016-11-18)Functional Principal Component Analysis (FPCA) approximates a sample curve as a linear combination of orthogonal basis functions. It is often possible to describe the essential parts of the variations of functional data ... -
Contributions to Functional Data Analysis With a Focus on Points of Impact in Functional Regression
(2018-05-16)The focus of this thesis is on the estimation of an unknown number of unknown specific locations (points of impact) at which a functional predictor has a specific effect on a real valued dependent variable.<br /> Two general ... -
Digital Filtering Algorithms for Decorrelation within Large Least Squares Problems
(2008)The GOCE (Gravity Field and steady-state Ocean Circulation Explorer) mission is dedicated to the determination of the Earth's gravity field. During the mission period of at least one year the GOCE satellite will collect ... -
Econometric Analysis of Financial Risk and Correlation
(2012-10-10)The contribution of this dissertation is threefold. First, econometric procedures to test for the occurence of asset price bubbles ex post and in real time are proposed. Real time monitoring procedures represent an additional ... -

(2011-07-12)Die Veränderung der Landbedeckung und Landnutzung durch den Menschen nimmt im Zusammenhang mit der Diskussion über die Folgen des globalen Umweltwandels seit vielen Jahren eine zentrale Rolle ein. In weiten Teilen West- ... -
Essays in Econometrics with focus on smooth minimum distance inference
(2021-08-04)This thesis consists of three self-contained essays in econometrics and statistics. It discusses methodological topics in semiparametric statistics as well as dynamic panel data models. In chapters 1 and 2 the smooth minimum ... -
Essays on Large Panel Data Models
(2015-06-09)The standard panel data literature is moving from micro panels, where the cross-section dimension is large and the intertemporal sample size is small, to large panels, where both, the cross-section and the time dimension, ... -
Ein Facettenmodell zur berufsbezogenen Persönlichkeit in Situationen organisationaler Veränderungen
(2013-07-11)Das Verhalten von Mitarbeitern im Kontext organisationaler (org.) Veränderungen kann besser beschrieben und erklärt werden, wenn Personen- und Situationsvariablen gemeinsam betrachtet werden (Blickle & Schneider, 2010; ... -
Finding gut microbiome signature in clinical intervention trials
(2025-02-17)The gut microbiome plays a crucial role in the gut brain axis, especially by modulating the immune system, influencing metabolism, protecting against pathogens, and impacting mental well-being. Therefore, it can be modulated ... -
Fortgeschrittene Methoden zur Modellierung von diskreten Ereigniszeiten
(2023-06-29)In longitudinalen klinischen Studien wird eine bestimmte Gruppe von Patienten/Patientinnen, die spezifische Einschlusskriterien erfüllt, über einen vorgegebenen Zeitraum hinweg beobachtet. Neben der Bestimmung von klinischen ... -
Four Essays in Econometrics and Macroeconomics
(2011-09-30)Chapter 1 proposes simple and robust diagnostic tests for spatial dependence, specifically for spatial error autocorrelation and spatial lag dependence. The idea of our tests is to reformulate the testing problem such that ... -
