  1. 26. On the efficiency of the Bayesian bootstrap

    Författare :Raul Cano; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Poisson-fördelning;

    Sammanfattning : The efficiency of the Bayesian bootstrap is treated for large and small samples from infinite and finite populations. The Bayesian bootstrap is compared with nonparametric and parametric Bayesian methods in the infinite case, for large samples and considering the mean and truncation functionals. LÄS MER

  3. 27. Optimal Design and Inference for Correlated Bernoulli Variables using a Simplified Cox Model

    Författare :Daniel Bruce; Hans Nyquist; Werner G. Müller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cox binary model; correlated binary data; log-odds ratio; D-optimality; E-optimality; power maximization; efficiency; Statistics; Statistik; statistik; Statistics;

    Sammanfattning : 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. LÄS MER

  4. 28. Data driven modeling in the presence of time series structure: : Improved bounds and effective algorithms

    Författare :Othmane Mazhar; Boualem Djehiche; Munther Dahleh; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time series; Non-asymptotic estimation; Minimax; Change point detection; Hidden Markov model; State space model; Least square; Penalized Regression; Random covariance matrix; Concentration inequality; Chaining integral; Self-normalized martingale inequality; Cramér-Rao inequality; van Trees inequality; Matematisk statistik; Mathematical Statistics;

    Sammanfattning : This thesis consists of five appended papers devoted to modeling tasks where the desired models are learned from data sets with an underlying time series structure. We develop a statistical methodology for providing efficient estimators and analyzing their non-asymptotic behavior. LÄS MER

  5. 29. Model calibration methods for mechanical systems with local nonlinearities

    Författare :Yousheng Chen; Andreas Linderholt; Thomas Abrahamsson; Gaëtan Kerschen; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model calibration; finite element modelling; nonlinear structural dynamics; pre-test planning; multi-sinusoidal excitation; vibrational testing; cross validation; Maskinteknik; Mechanical Engineering;

    Sammanfattning : Most modern product development utilizes computational models. With increasing demands on reducing the product development lead-time, it becomes more important to improve the accuracy and efficiency of simulations. LÄS MER

  7. 30. Benefits of Non-Linear Mixed Effect Modeling and Optimal Design : Pre-Clinical and Clinical Study Applications

    Författare :Charles Ernest II; Andrew Hooker; Mats Karlsson; Bart Ploeger; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacometrics; optimal design; nonlinear mixed effects models; population models; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : Despite the growing promise of pharmaceutical research, inferior experimentation or interpretation of data can inhibit breakthrough molecules from finding their way out of research institutions and reaching patients. This thesis provides evidence that better characterization of pre-clinical and clinical data can be accomplished using non-linear mixed effect modeling (NLMEM) and more effective experiments can be conducted using optimal design (OD).
