  1. 6. Optimal Design and Inference for Correlated Bernoulli Variables using a Simplified Cox Model

    University dissertation from Stockholm : Statistiska institutionen

    Author : Daniel Bruce; Stockholms universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cox binary model; correlated binary data; log-odds ratio; D-optimality; E-optimality; power maximization; efficiency; SOCIAL SCIENCES Statistics; computer and systems science Statistics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Statistik; statistik; Statistics;

    Abstract : This thesis proposes a simplification of the model for dependent Bernoulli variables presented in Cox and Snell (1989). The simplified model, referred to as the simplified Cox model, is developed for identically distributed and dependent Bernoulli variables. READ MORE

    Abstract : In this Ph.D. thesis, we investigate how to optimize the design of clinical trials by constructing optimal adaptive designs, and how to implement the design by adaptive randomization. READ MORE

  3. 8. Biochemical Interactions of Some Saproxylic Fungi

    University dissertation from Sundsvall : Mid Sweden University

    Author : Joel Ljunggren; Mittuniversitetet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biologically active compounds; bioactive; fungi-fungi interaction; fungi co-culture; extracellular amino acids.;

    Abstract : Interactions are all around us, and as humans we may use words and gestures to communicate our intentions. At the micro level of fungi, communications are replaced by chemical signals and structure. READ MORE
