1. Bayesian Cluster Analysis : Some Extensions to Non-standard Situations
Sammanfattning : The Bayesian approach to cluster analysis is presented. We assume that all data stem from a finite mixture model, where each component corresponds to one cluster and is given by a multivariate normal distribution with unknown mean and variance. LÄS MER
2. Return Migration from Sweden : A Longitudinal Analysis
Sammanfattning : Return migration is one of the least studied areas within migration research, although it has major implications for both sending and receiving societies. The importance of the phenomenon is shown by the fact that more than 50 percent of the immigrants who arrived in Sweden in 1970 had returned after twenty years. LÄS MER
3. Learning Computing at University: Participation and Identity : A Longitudinal Study
Sammanfattning : Computing education has struggled with student engagement and diversity in the student population for a long time. Research in science, technology, engineering, and mathematics (STEM) education suggests that taking a social, long-term perspective on learning is a fruitful approach to resolving some of these persistent challenges.

4. Life paths through space and time: Adding the micro-level geographic context to longitudinal historical demographic research
Sammanfattning : Historical demographic research is central to understanding past human behaviours and traits, such as fertility, mortality and migration. An essential part of historical demography is conducting longitudinal analyses at the micro-level, which involves the detailed follow-up of individuals over long time periods throughout their lives.

5. Nonlinear Quantile Regression for Longitudinal Data
Sammanfattning : 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. LÄS MER
