1. On the Treatment of Flow in Traffic Safety Analysis, - a non-parametric approach applied on vulnerable road users
Abstract : The treatment of flow in the area of traffic safety has a long tradition. The influence flow has on the number of accidents is, however, often considered so obvious that it tends to be trivial. In this thesis I can show that the relation between flow and accidents holds interesting information. READ MORE

2. On Bootstrap Evaluation of Tests for Unit Root and Cointegration
Abstract : This thesis is comprised of five papers that all relate to bootstrap methodology in analysis of non-stationary time series.The first paper starts with the fact that the Dickey-Fuller unit root test using asymptotic critical value has bad small sample performance. READ MORE

3. Estimation and Inference for Quantile Regression of Longitudinal Data : With Applications in Biostatistics
Abstract : This thesis consists of four papers dealing with estimation and inference for quantile regression of longitudinal data, with an emphasis on nonlinear models.The first paper extends the idea of quantile regression estimation from the case of cross-sectional data with independent errors to the case of linear or nonlinear longitudinal data with dependent errors, using a weighted estimator.

4. Nonlinear Quantile Regression for Longitudinal Data
Abstract : The overall objective of the two papers in this thesis is to examine the properties of the weighted nonlinear quantile regression estimator for the analysis of longitudinal data. To this end, the question of which weights to be used, the bias of the estimator and the possibility to calculate confidence intervals has to be examined. READ MORE

5. Estimators of semiparametric truncated and censored regression models
Abstract : This thesis contributes in several ways to the existing knowledge on estimation of truncated, censored, and left truncated right censored (LTRC) regression models. Three new semiparametric estimators are proposed, allowing for asymmetric error distributions. READ MORE
