  6. 4. On Sequential Treatment Allocations in Clinical Trials

    Author : Carl-Fredrik Burman; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; treatment assignment; clinical trial; biased coin designs; balance of prognostic factors; sequential design; randomization test; expected p-value; deficiency; efficiency; efficiency;

    Abstract : This dissertation treats baseline-dependent sequential designs of two-treatment parallel-group clinical trials. The treatment assignments are chosen in order to minimize the variance, in a linear model, of the treatment effect. This is done for each new allocation using a generalized biased coin design, or a non-randomized minimization' method. READ MORE

  7. 5. Optimal Sequential Decisions in Hidden-State Models

    Author : Juozas Vaicenavicius; Erik Ekström; Huyên Pham; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sequential analysis; optimal stopping; optimal liquidation; drift uncertainty; incomplete information; stochastic filtering;

    Abstract : This doctoral thesis consists of five research articles on the general topic of optimal decision making under uncertainty in a Bayesian framework. The papers are preceded by three introductory chapters.Papers I and II are dedicated to the problem of finding an optimal stopping strategy to liquidate an asset with unknown drift. READ MORE
