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

    Författare :Ellinor Fackle Fornius; Hans Nyquist; Christos Kitsos; Stockholms universitet; []
    Nyckelord :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

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

    Författare :Sharon Kühlmann-Berenzon; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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
