  1. 1. On Methods for Real Time Sampling and Distributions in Sampling

    Detta är en avhandling från Umeå : Matematisk statistik

    Författare :Kadri Meister; Umeå universitet.; [2004]
    Nyckelord :MATEMATIK; MATHEMATICS; Mathematical statistics; Finite population sampling; inferential issues; real time sampling; sequential sampling methods; negative sampling correlations; model-design-based inference; multivariate Bernoulli and multinomial designs; Matematisk statistik; Mathematical Statistics; matematisk statistik;

    Sammanfattning : This thesis is composed of six papers, all dealing with the issue of sampling from a finite population. We consider two different topics: real time sampling and distributions in sampling. The main focus is on Papers A–C, where a somewhat special sampling situation referred to as real time sampling is studied. LÄS MER

  3. 2. Approximation of Infinitely Divisible Random Variables with Application to the Simulation of Stochastic Processes

    Detta är en avhandling från Centre for Mathematical Sciences, Mathematical Statistics, Box 118, 221 00 Lund

    Författare :Magnus Wiktorsson; Lunds universitet.; Lund University.; [2001]
    Nyckelord :MATEMATIK; MATHEMATICS; Mathematics; Matematik; Mathematical Statistics; Stochastic integral; Lévy process; Type G distribution; Infinitely divisible distribution; Stochastic differential equation; aktuariematematik; Statistics; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering;

    Sammanfattning : This thesis consists of four papers A, B, C and D. Paper A and B treats the simulation of stochastic differential equations (SDEs). The research presented therein was triggered by the fact that there were not any efficient implementations of the higher order methods for simulating SDEs. LÄS MER

  4. 3. Statistical methods for knowledge discovery in adverse drug reaction surveillance

    Detta är en avhandling från Stockholm : Matematiska institutionen

    Författare :G. Niklas Norén; Stockholms universitet.; [2007]
    Nyckelord :MATEMATIK; MATHEMATICS; matematisk statistik; Mathematical Statistics;

    Sammanfattning : Collections of individual case safety reports are the main resource for early discovery of unknown adverse reactions to drugs once they have been introduced to the general public. The data sets involved are complex and based on voluntary submission of reports, but contain pieces of very important information. LÄS MER

  5. 4. Filter Bank Techniques for Signal and Image Processing

    Detta är en avhandling från Stockholm : Matematiska institutionen

    Författare :Farook Sattar; Lunds universitet.; Lund University.; [1996]
    Nyckelord :TEKNIKVETENSKAP; TECHNOLOGY; Higher-order statistics; Imaging; Detection; Echo cancelling; Multirate system; Multiscale; Image enhancement; Time-frequency analysis and synthesis; Non-stationary signals; Filter bank; Non-parametric estimation; image processing; Bildbehandling; Signal processing; Signalbehandling;

    Sammanfattning : This thesis consists of five parts, each of which considers methods based on filter banks for different applications in signal and image processing. In Part I, a non-parametric estimation method is proposed using filter banks to estimate signals with varying waveforms and arrival times. LÄS MER

  7. 5. Multivariable Orthogonal Polynomials as Coupling Coefficients for Lie and Quantum Algebra Representations

    Detta är en avhandling från Centre for Mathematical Sciences, Mathematics (Faculty of Science), Lund University, Box 118, SE-221 00 Lund, Sweden

    Författare :Hjalmar Rosengren; Lunds universitet.; Lund University.; [1999]
    Nyckelord :MATEMATIK; MATHEMATICS; Wigner symbol; higher order Hankel form; quadratic algebra; Clebsch-Gordan coefficient; quantum group; Lie group; highest weight representation; multivariable orthogonal and biorthogonal polynomials; multivariable hypergeometric and basic hypergeometric functions; algebraisk topologi; Geometry; Geometri; algebraic topology;

    Sammanfattning : The main topic of the thesis is the connection between representation theory and special functions. We study matrix elements, coupling coefficient, and recoupling coefficients for the simplest Lie and quantum groups. LÄS MER
