    Nyckelord :Regression; near-infrared calibration; microarray; mixed model; logistic regression; random effects; variable selection; differential expression; mixture distribution;

    Sammanfattning : This thesis focuses on regression methodology for prediction and classification in situations where there are many predictors but limited number of observations. This situation is common in chemometrics and microarray data. LÄS MER

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

    Författare :Anna Grimby-Ekman; Göteborgs universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 25. Calibration Adjustment for Nonresponse in Sample Surveys

    Författare :Bernardo João Rota; Thomas Laitila; Sune Karlsson; Risto Lehtonen; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Auxiliary variables; Calibration; Nonresponse; principal com-ponents; regression estimator; response probability; survey sampling; two-step estimator; variance estimator; weighting; Statistics; Statistik;

    Sammanfattning : In this thesis, we discuss calibration estimation in the presence of nonresponse with a focus on the linear calibration estimator and the propensity calibration estimator, along with the use of different levels of auxiliary information, that is, sample and population levels. This is a fourpapers- based thesis, two of which discuss estimation in two steps. LÄS MER
