  1. 1. Some properties of measures of disagreement and disorder in paired ordinal data

    Författare :Hans Högberg; Elisabeth Svensson; Sture Holm; Örebro universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; agreement; augmented ranks; categorical data; disorder; jackknife; paired ordinal data; rating scales; sample size; sampling distribution; simulation; U-statistics; variance; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Statistics; Statistik; Statistics; Statistik;

    Sammanfattning : The measures studied in this thesis were a measure of disorder, D, and a measure of the individual part of the disagreement, the measure of relative rank variance, RV, proposed by Svensson in 1993. The measure of disorder is a useful measure of order consistency in paired assessments of scales with a different number of possible values. LÄS MER

  2. 2. Optimal Sequential Decisions in Hidden-State Models

    Författare :Juozas Vaicenavicius; Erik Ekström; Huyên Pham; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; sequential analysis; optimal stopping; optimal liquidation; drift uncertainty; incomplete information; stochastic filtering;

    Sammanfattning : This doctoral thesis consists of five research articles on the general topic of optimal decision making under uncertainty in a Bayesian framework. The papers are preceded by three introductory chapters.Papers I and II are dedicated to the problem of finding an optimal stopping strategy to liquidate an asset with unknown drift. LÄS MER

  3. 3. Statistical methods for early discovery of diabetic neuropathy using epidermal nerve fiber data

    Författare :Claes Andersson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diabetic neuropathy; Epidermal nerve fibers; Hierarchical models; Point processes; Reactive territory; Diabetic neuropathy;

    Sammanfattning : The main aim with the work in this thesis is to increase the understanding of the effects diabetic neuropathy has on the epidermal nerve fibers and thereby find methods to detect the disorder at an earlier stage. Epidermal nerve fibers (ENFs) are small sensory nerve fibers in the skin, sensing heat and pain. LÄS MER

  4. 4. Craniofacial malformations and psychiatric disorders from a neurodevelopmental perspective

    Författare :Karin K. Tillman; Fotios Papadopoulos; Lisa Ekselius; Mia Ramklint; Daniel Nowinski; Clara Hellner; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nonsyndromic orofacial clefts; Nonsyndromic craniosynostosis; Neurodevelopmental disorders; Psychiatric disorders; Educational achievements; Child and Youth Psychiatry; Barn- och ungdomspsykiatri;

    Sammanfattning : Orofacial clefts (OFC) and craniosynostosis (CS) are the two most common craniofacial malformations. Of note, craniofacial abnormalities share some overlapping risk factors with psychiatric disorders. Thus, this thesis aimed to study psychiatric and educational outcomes in this group. LÄS MER

  5. 5. Risks, correlates, and consequences of the extended psychosis phenotype

    Författare :Martin Cederlöf; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Psychotic disorders such as schizophrenia entail substantial suffering for the affected individuals and their networks. Traditionally, these disorders come as diagnosable entities that you either have or have not. However, recent epidemiological research has shown that symptoms of psychotic disorder, i.e. LÄS MER
