  3. 12. Uncertainty intervals and sensitivity analysis for missing data

    Författare :Minna Genbäck; Xavier de Luna; Elena Stanghellini; Arvid Sjölander; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; missing data; missing not at random; non-ignorable; set identification; uncertainty intervals; sensitivity analysis; self reported health; average causal effect; average causal effect on the treated; mixed-effects models; Statistics; statistik;

    Sammanfattning : In this thesis we develop methods for dealing with missing data in a univariate response variable when estimating regression parameters. Missing outcome data is a problem in a number of applications, one of which is follow-up studies. LÄS MER

  5. 14. Properties of heavy rainfall in an East Asian monsoon catchment - Analysis of daily rain gauge data

    Författare :Cecilia Svensson; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; China.; Huai River; East Asian monsoon; typhoon; Mei-Yu front; fractals; empirical orthogonal function analysis; correlation analysis; probable maximum precipitation; storm movement; seasonal occurrence; Rainfall; spatial pattern; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Sammanfattning : The East Asian monsoon has a strong seasonal effect on the rainfall regime of Eastern China. In order to mitigate floods and conserve the water for use throughout the year, dams and other hydro-structures are built. The design of the structures requires knowledge of the rainfall characteristics that influence the inflow to them. LÄS MER

  7. 15. A Unified Framework for Indeterminate Probabilities and Utilities

    Författare :Love Ekenberg; Johan Thorbiörnson; Yuri Ermoliev; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Decision Analysis; Risk Analysis; Second order probabilities; MATHEMATICS; MATEMATIK;

    Sammanfattning : In classic decision theory, the different alternatives in a decision situation are merely objects of choice, and it is assumed that a decision maker can assign precise numerical values corresponding to the true value of each consequence, as well as precise numerical probabilities for their occurrences. However, in real-life situations, the ordering of alternatives from most to least preferred is often a delicate matter and an adequate mathematical representation is crucial. LÄS MER
