  2. 1. Bayesian Cluster Analysis : Some Extensions to Non-standard Situations

    Author : Jessica Franzén; Daniel Thorburn; Jukka Corander; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cluster analysis; Clustering; Classification; Mixture model; Gaussian; Bayesian inference; MCMC; Gibbs sampler; Deviant group; Longitudinal; Missing data; Multiple imputation; Statistics; Statistik; Statistics; statistik;

    Abstract : The Bayesian approach to cluster analysis is presented. We assume that all data stem from a finite mixture model, where each component corresponds to one cluster and is given by a multivariate normal distribution with unknown mean and variance. READ MORE

  4. 2. Latent Trait Models of Intrinsic, Extrinsic, and Quest Religious Orientations

    Author : Marcus Koskinen-Hagman; Centrum för teologi och religionsvetenskap; []
    Keywords : HUMANIORA; HUMANITIES; Theology; Meta-analysis; Item Analysis; Rasch; Scaling; Quest; Extrinsic; Intrinsic; Measurement; Religious Orientations; Teologi;

    Abstract : Allports and Ross (1967) Intrinsic and Extrinsic scales and Batsons and Schoenrades (1991b) Quest scale are re-analyzed from a unidimensional perspective by using the Rasch measurement model (RM). The RM of choice, Rating scale analysis, offers an alternative scaling procedure to Factor analysis. READ MORE

  5. 3. Pharmacometric Investigations of Prediction Precision and Advances of Models for Composite Scale Data

    Author : Gustaf Wellhagen; Maria C. Kjellsson; Bengt Hamrén; Per Olsson Gisleskog; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacometrics; modelling; non-linear mixed effects modelling; composite scale data; total score data; total score analysis; precision prediction; bounded integer; bounded integer model; IRT-informed total score analysis; item response theory-informed; mixed models for repeated measures; MMRM; dose-response; dose-response mixed models for repeated measures; DR-MMRM; HbA1c models; fit-for-purpose analysis; clinical trial analysis; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : Clinical trials are needed to evaluate new treatments. In late-stage clinical trials, failures are mostly due to lack of efficacy. Fit-for-purpose analysis methods will likely increase the success rates and advance drug development by providing higher precision to support decisions such as go/no-go, dose selection, or sample size.

    Abstract : Background. Police work is a stressful occupation with frequent exposure to traumatic events and psychological strain from work might increase the risk of burnout. This thesis focuses on patrolling police officers (PPO), who work most of their time in the community and have daily contact with the public. READ MORE

  7. 5. Women's evaluations of intrapartum and postpartum care

    Author : Ann Ingmarsdotter Rudman; Karolinska Institutet; Karolinska Institutet; Karolinska Institutet Institutionen för kvinnors och barns hälsa / Department of Women's and Children's Health; []

    Abstract : The overall aim of this thesis was to increase understanding of women s evaluations of intrapartum and postpartum care. Evaluations of specific aspects of care, general assessments of intrapartum and postpartum care, and predictors of not being satisfied were investigated, as well as negative experiences of postpartum care, as expressed in women s own words.
