  2. 1. Computational Medical Image Analysis : With a Focus on Real-Time fMRI and Non-Parametric Statistics

    Author : Anders Eklund; Hans Knutsson; Mats Andersson; Stephen LaConte; Linköpings universitet; []
    Keywords : functional magnetic resonance imaging; brain computer interfaces; canonical correlation analysis; random permutation test; graphics processing unit;

    Abstract : Functional magnetic resonance imaging (fMRI) is a prime example of multi-disciplinary research. Without the beautiful physics of MRI, there wouldnot be any images to look at in the first place. To obtain images of goodquality, it is necessary to fully understand the concepts of the frequencydomain. READ MORE

  4. 2. Methods for interval-censored data and testing for stochastic dominance

    Author : Angel G. Angelov; Magnus Ekström; Maria Karlsson; Bengt Kriström; Per Johansson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interval-censored data; Informative censoring; Self-selected intervals; Questionnaire-based studies; Maximum likelihood; Permutation test; Two-sample test; Stochastic dominance; Four-decision test; Statistics; statistik;

    Abstract : This thesis includes four papers: the first three of them are concerned with methods for interval-censored data, while the forth paper is devoted to testing for stochastic dominance.In many studies, the variable of interest is observed to lie within an interval instead of being observed exactly, i.e. READ MORE

  5. 3. Protein Folding Studies on the Ribosomal Protein S6: the Role of Entropy in Nucleation

    Author : Magnus Lindberg; Mikael Oliveberg; Jane Clarke; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; protein folding; circular permutation; topology; connectivity; entropy; protein stability; chevron plot; Biokemi; Biochemistry; Biokemi; Biochemistry; biokemi;

    Abstract : One of the most challenging tasks remaining in the field of biochemistry is the one of understanding how the information within the amino acid sequence of proteins translates into a unique structure. Solving this problem would lead to endless possibilities for application in the medical and biotechnology industry. READ MORE

  6. 4. Spatial Statistics and Ancestral Recombination Graphs with Applications in Gene Mapping and Geostatistics

    Author : Linda Werner Hartman; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genetik; Genetics; cytogenetics; cytogenetik; genetic association analysis; ancestral recombination graph Generalized linear mixed models; kriging; bilinear interpolation; Gaussian Markov random fields; Statistics;

    Abstract : This thesis explores models and algorithms in geostatistics and gene mapping. The first part deals with the use of computationally effective lattice models for inference of data with a continuous spatial index. READ MORE

  7. 5. Aspects of multilinear algebra in statistical analysis of seasonal multivariate time series

    Author : Björn Holmquist; Statistiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Representations of concepts from multivariate statistics are studied using multilinear algebra. Applications are given to the analysis of seasonal multivariate time series. The first paper concerns a class of permutation matrices which are representations of permutation operators on tensor spaces. READ MORE
