Bandwidth Selection in Nonparametric Kernel Estimation
(2012-03-14)Kernel estimation is a common nonparametric method for data based estimation of densities or regression functions. Although one may consider nonparametric estimation as a procedure that ... -
Econometric studies on flexible modeling of developing countries in growth analysis
(2012-05-25)Over the last four decades, several methods for selecting the smoothing parameter, generally called the bandwidth, have been introduced in kernel regression. They differ quite a bit, and although there already exist ... -
Okonometrische Verfahren zur Messung von Segregation und Lohndiskriminierung - eine theoretische und empirische Studie
(2013-01-31)In most economies males earn higher wages than females. The question is whether this wage gap is due to discrimination or not. The dominant approach is the human capital theory by Becker and Mincer. It means that workers ... -
Semiparametric Structure Guided by Prior Knowledge with Applications in Economics
(2011-05-27)Among many developments in statistical modelling in recent years, non- and semiparametric methods have proved to be a particularly powerful data-analytic tool. Nevertheless, there still ... -
Simple Solutions to hard Problems in the Estimation and Prediction of Welfare Distributions
(2011-06-01)The aim of my PhD projects is to investigate various problems in applied parametric and nonparametric estimation, and eventually in prediction. The main focus is on welfare analysis. For instance, in both nonparametric density ... -
Three Essays on Application of Semiparametric Regression: Partially Linear Mixed Effects Model and Index Model
(2012-12-07)The dissertation consists of three essays. The main focus is set on semiparametric regression modeling, which embodies the strength of parametric and nonparametric regression models in terms of flexibility, dimensionality ... -
Three studies on semi-mixed effects models
(2012-01-05)The applications of non- and semiparametric models are found in nearly all fields of empirical research. Since nonparametric methods do not have restrictive assumptions about the distribution of the observations ...
