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

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

    Sammanfattning : 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. LÄS MER

  2. 2. Evaluation of Students' Attitudes Towards Vocational Education in Jordan

    Författare :Ahmed Al-Sa'd; Malmö högskola; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; attitudes; students attitudes; vocational education; psychometrics; scaling techniques; factor analysis; multiple regression; logistic regression; attitude behaviour relationship;

    Sammanfattning : This doctoral dissertation consists of the empirical main study and the explorative study. The main goal of the empirical study has been to acquire knowledge about students’ attitudes towards vocational education in Jordan, and to explore the dimensionality of their attitudes as well.

  3. 3. Edge correction and regression models for quantifying single-tree influence on understory vegetation

    Författare :Sharon Kühlmann-Berenzon; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :beta distribution; ecology; edge effects; forestry; influence potential; logistic regression; statistical modeling; spatial point process; statistical modeling;

    Sammanfattning : The understory is the layer of vegetation in the forest situated under the canopies of the trees. Some species of understory vegetation benefit from the surrounding trees, e.g by the provided nutrients, while others are restricted, e.g. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Statistik; operationsanalys; programmering; aktuariematematik; programming; actuarial mathematics; Statistics; operations research; experimental design.; logistic regression; detection probability; region of operability; sampling. Diagnostic PCR; Cramér-Rao bounds; maximum likelihood estimation; NMR spectroscopy; Gaussian noise;

    Sammanfattning : This thesis consists of two parts with the common theme of statistical modelling in chemistry. The first part is concerned with applications in nuclear magnetic resonance (NMR) spectroscopy, while the second part deals with applications in polymerase chain reaction (PCR). LÄS MER
