2. 1. Optimal Design of Experiments for the Quadratic Logistic Model

   Author : Ellinor Fackle Fornius; Hans Nyquist; Christos Kitsos; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Logistic regression; D-optimality; c-optimality; Canonical design space; Maximum likelihood estimation; Sequential design; Stochastic approximation; Statistics; Statistik; statistik; Statistics;

   Abstract : Optimal design of experiments for binary data is the topic of this thesis. A particular logistic model including a quadratic term in the linear predictor is considered. Determining an optimal design for this model is complicated by the fact that the optimal design is dependent on the unknown true parameters. READ MORE

4. 2. Epidemiological aspects of musculoskeletal pain in the upper body. Analyzing common and recurrent binary outcomes

   Author : Anna Grimby-Ekman; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; musculoskeletal; pain; neck; repeated measurements; logistic model; odds ratio OR ; risk ratio RR ; risk difference RD ; biological interaction;

   Abstract : The overall aim of this thesis is to gain epidemiological knowledge about musculoskeletal pain in the upper body in light physical work, in relation to gender, psychosocial factors, and computer use; and to compare different methods for analyzing common and recurrent binary outcomes. Two study groups were investigated using questionnaire data: (a) computer users in the Swedish workforce and (b) a cohort of university students. READ MORE

5. 3. Generalised linear models with clustered data

   Author : Henrik Holmberg; Göran Broström; Kenneth Carling; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; Statistik; Statistics; statistik;

   Abstract : In situations where a large data set is partitioned into many relativelysmall clusters, and where the members within a cluster have some common unmeasured characteristics, the number of parameters requiring estimation tends to increase with sample size if a fixed effects model is applied. This fact causes the assumptions underlying asymptotic results to be violated. READ MORE

6. 4. To get things done, the challenge in everyday life for children with spina bifida. Quality of performance, autonomy and participation

   Author : Marie Peny-Dahlstrand; Göteborgs universitet; []
   Keywords : spina bifida; myelomeningocele; lipo-myelomenigocele; performance skills; autonomy; participation; Assessment of Motor and Process Skills AMPS ; School Function Assessment SFA ;

   Abstract : The overall aim of this thesis was to increase knowledge of the quality of performance of everyday activities, autonomy and participation in children with spina bifida (SB) and to explore how they relate to each other. Methods: In Study I, the quality of performance of everyday activities in 50 children with SB (of the 65 in a population-based cohort) aged 6 to14 years was assessed with the Assessment of Motor and Process Skills (AMPS).

7. 5. Generalized linear models with clustered data

   Author : Henrik Holmberg; Erling Häggström Lundevaller; Göran Broström; Douglas Bates; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; statistik;

   Abstract : In situations where a large data set is partitioned into many relatively small groups, and where the members within a group have some common unmeasured characteristics, the number of parameters requiring estimation tends to increase with sample size if a fixed effects model is applied. This fact causes the assumptions underlying asymptotic results to be violated. READ MORE
