  1. 1. Intelligence and models for cognitive development

    University dissertation from Stockholm : Statistiska institutionen

    Author : Linda Wänström; Stockholms universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; intelligence; cognitive development; sample size; multilevel models; latent growth curve models; SOCIAL SCIENCES Statistics; computer and systems science Statistics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Statistik; statistik; Statistics;

    Abstract : This dissertation focuses on cognitive development. In papers I and II, I study a special model, the second order latent growth curve model, that can be used to study cognitive development. Algebraic expressions for the variance of the estimation of slope differences are given. READ MORE

  2. 2. Understanding therapeutic traditions in a multilevel framework - new methodological approaches

    University dissertation from Unit for Social Epidemiology, Deptartment of Clinical Sciences, Faculty of Medicine, Lund University

    Author : Henrik Ohlsson; Lund University.; Lunds universitet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adherence to guidelines; practice variation; Multilevel models; variance components; determinants of prescription;

    Abstract : Background: The observation of differences in the way apparently similar patients are treated from one health care setting to another, i.e., practice variation, have been recognized in numerous studies. The variations across the health care settings have been shown to exist for different outcomes. READ MORE

  3. 3. A study of multilevel models with block circular  symmetric covariance structures

    University dissertation from Stockholm : Department of Statistics, Stockholm University

    Author : Yuli Liang; Stockholms universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistik; Statistics; Block circular symmetry; Covariance matrix; Explicit solution; Maximum likelihood estimator; Multilevel model; Spectrum;

    Abstract : This thesis concerns the study of multilevel models with specific patterned covariance structures and addresses the issues of maximum likelihoodestimation. In particular, circular symmetric hierarchical datastructures are considered. READ MORE

  4. 4. Spatial analysis and modeling of nerve fiber patterns

    University dissertation from Göteborg : Chalmers tekniska högskola

    Author : Claes Andersson; Göteborgs universitet.; Gothenburg University.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bayesian field theory; Diabetic neuropathies; Multilevel models Statistics ; Institutionen för matematiska vetenskaper. Tillämpad matematik och statistik.; CTH; hierarchical models; Bayesian estimation; epidermal nerve fibers; cluster processes; spatial point processes; diabetic neuropathy;

    Abstract : Diabetic neuropathy is a condition associated with diabetes affecting the epidermal nerve fibers (ENFs). This thesis presents analysis methods and models for ENF data, with two main puroposes: to find early signs of diabetic neuropathy and to characterize how this condition changes the nerve fiber structure.

  5. 5. Managing the Transformation Towards Advanced Service Provision A Multilevel Framework of Servitization

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Sambit Lenka; Luleå tekniska universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Entreprenörskap och innovation; Entrepreneurship and Innovation; Servitization; Advanced Services; Multilevel; Transformation; Ambivalence; Microfoundations; Capabilities;

    Abstract : Product-oriented firms are increasingly moving towards providing services to customers in a bid to differentiate their offerings, increase customer loyalty, and achieve higher, more stable revenue streams. This trend of servitization is becoming ubiquitous in manufacturing firms. READ MORE
