    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Sentence adverbials; information dynamics; word order; constituent order; Swedish; information structure; Lexical-Functional Grammar; Optimality Theory;

    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

  3. 12. Optimal Subsampling Designs Under Measurement Constraints

    Författare :Henrik Imberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; inverse probability weighting; unequal probability sampling; optimal design; active sampling; M-estimation;

    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

  4. 13. Univariate and Multivariate Surveillance of Outbreaks

    Författare :Linus Schiöler; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; change-points; expected delay; exponential family; false alarms; generalised likelihood; inference principles; influenza; MEWMA; monitoring; multivariate; ordered regression; performance metrics; outbreak; predictive value; subjective judgment; spatial; statistical models; surveillance; tularemia;

    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.

  5. 14. Contributions to the Stochastic Maximum Principle

    Författare :Daniel Andersson; Boualem Djehiche; Fred Espen Benth; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Matematisk statistik;

    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.

  7. 15. Topics in Mean-Field Control and Games for Pure Jump Processes

    Författare :Salah Eddine Choutri; Boualem Djehiche; Marco Fuhrman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    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.
