11. Satsadverbial, ledföljd och informationsdynamik i svenskan
Sammanfattning : The first aim of this thesis is to investigate causes behind constituent order variation in Swedish main clauses. The second aim is to explore pragmatic and distributional di... LÄS MER
12. Optimal Subsampling Designs Under Measurement Constraints
Sammanfattning : We consider the problem of optimal subsample selection in an experiment setting where observing, or utilising, the full dataset for statistical analysis is practically unfeasible. This may be due to, e.g., computational, economic, or even ethical cost-constraints. LÄS MER
13. Univariate and Multivariate Surveillance of Outbreaks
Sammanfattning : In many areas there is a need to monitor observations in order to detect changes in the underlying processes as quickly as possible. The theory of statistical surveillance provides the possibility of making optimal decisions about whether a change has occurred or not based on the data available at the time of the decision. LÄS MER
14. Contributions to the Stochastic Maximum Principle
Sammanfattning : This thesis consists of four papers treating the maximum principle for stochastic control problems. In the first paper we study the optimal control of a class of stochastic differential equations (SDEs) of mean-field type, where the coefficients are allowed to depend on the law of the process.

15. Topics in Mean-Field Control and Games for Pure Jump Processes
Sammanfattning : This thesis is the collection of four papers addressing topics in stochastic optimal control, zero-sum games, backward stochastic differential equations, Pontryagin stochastic maximum principle and relaxed stochastic optimal control.In the first two papers, we establish existence of Markov chains of mean-field type, with countable state space and unbounded jump intensities.
