  1. 6. Rao-Blackwellised particle methods for inference and identification

    Författare :Fredrik Lindsten; Thomas Schön; Lennart Ljung; Fredrik Gustafsson; Tobias Rydén; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : We consider the two related problems of state inference in nonlinear dynamical systems and nonlinear system identification. More precisely, based on noisy observations from some (in general) nonlinear and/or non-Gaussian dynamical system, we seek to estimate the system state as well as possible unknown static parameters of the system.

  3. 7. Method developments for the attributable fraction in causal inference

    Författare :Elisabeth Dahlqwist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In public health and policy making, understanding the overall impact of an intervention is of essential importance. A way to quantify the disease burden due to some risk factor is by the attributable fraction (AF). LÄS MER

  4. 8. Models for Additive and Sufficient Cause Interaction

    Författare :Daniel Berglund; Timo Koski; Helga Westerlind; Ola Hössjer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Causal Inference; Sufficient Cause; Potential Outcomes; Counterfactual; Additive Interaction; Interaction; MFPO; ICI; Logistic Regression; Linear Odds; Public Health; Interventions; Probabilistic Potential Outcome; Matematisk statistik; Mathematical Statistics;

    Sammanfattning : The aim of this thesis is to develop and explore models in, and related to, the sufficient cause framework, and additive interaction. Additive interaction is closely connected with public health interventions and can be used to make inferences about the sufficient causes in order to find the mechanisms behind an outcome, for instance a disease.

  5. 9. Evolutionary Studies in Asterids Emphasising Euasterids II

    Författare :Jesper Kårehed; Mats H. G. Gustafsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organismic biology; Apiales; Aquifoliales; Asterales; asterids; Bayesian inference; Cardiopteridaceae; DNA sequence data; Icacinaceae; morphology; parsimony; Pennantiaceae; phylogeny; Stemonuraceae; Organismbiologi; Organism biology; Organismbiologi; systematisk botanik; Systematic Botany;

    Sammanfattning : This thesis deals with evolutionary relationships within the asterids, a group of plants comprising about one-third of all flowering plants.Two new families are recognised: Pennantiaceae and Stemonuraceae. The woody Pennantia from New Zealand and Australia is the sole genus of Pennantiaceae. LÄS MER

  7. 10. Non-Gaussian Statistical Modelsand Their Applications

    Författare :Zhanyu Ma; Arne Leijon; Cédric Févotte; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Statistical modeling plays an important role in various research areas. It provides away to connect the data with the statistics. Based on the statistical properties of theobserved data, an appropriate model can be chosen that leads to a promising practicalperformance. LÄS MER
