  1. 11. Statistical modeling in international large-scale assessments

    Författare :Inga Laukaityte; Marie Wiberg; Kenny Bränberg; Ewa Rolfsman; Bernard Veldkamp; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multilevel model; plausible values; sampling weights; missing information; multiple imputation; non-monotone missing pattern; TIMSS; PISA; Statistics; statistik; pedagogik; Education;

    Sammanfattning : This thesis contributes to the area of research based on large-scale educational assessments, focusing on the application of multilevel models. The role of sampling weights, plausible values (response variable imputed multiple times) and imputation methods are demonstrated by simulations and applications to TIMSS (Trends in International Mathematics and Science Study) and PISA (Programme for International Student Assessment) data.

  3. 12. Equity in welfare evaluations : the rationale for and effects of distributional weighting

    Författare :Gunnel Bångman; Lars Hultkrantz; Fredrik Carlsson; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; weighted cost-benefit analysis; equity; distributional weights; social welfare; income distribution; risk aversion; social marginal value of income; altruism; paternalism; marginal utility of income; social inequality aversion; stated preferences; Economics; Nationalekonomi; Economics; Nationalekonomi;

    Sammanfattning : This thesis addresses the issue of weighted cost-benefit analysis (WCBA). WCBA is a welfare evaluation model where income distribution effects are valued by distributional weighting. The method was developed already in the 1970s. The interest in and applications of this method have increased in the past decade, e. LÄS MER

  4. 13. Cost-Benefit Analysis of climate policy and long term public investments

  7. 15. On determinantal point processes and random tilings with doubly periodic weights

    Författare :Tomas Berggren; Maurice Duits; Neil O'Connell; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Determinantal point processes; Periodically weighted random tilings; Central Limit Theorems; Riemann-Hilbert problems; Mathematics; Matematik;

    Sammanfattning : This thesis is dedicated to asymptotic analysis of determinantal point processes originating from random matrix theory and random tiling models. Our main interest lies in random tilings of planar domains with doubly periodic weights. LÄS MER
