  2. 17. On the Application of the Bootstrap Coefficient of Variation, Contingency Table, Information Theory and Ranked Set Sampling

    Detta är en avhandling från Uppsala : Department of Mathematics

    Författare :Saeid Amiri; Uppsala universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bootstrap method; Categorical data; Coefficient of variation; Entropy; Exponential family; Monte Carlo investigation; Informational energy; Ranked set sampling; Variance-stabilization transformation; Statistics; Statistik;

    Sammanfattning : This thesis deals with the bootstrap method. Three decades after the seminal paper by Bradly Efron, still the horizons of this method need more exploration. The research presented herein has stepped into different fields of statistics where the bootstrap method can be utilized as a fundamental statistical tool in almost any application. LÄS MER

  4. 19. On methods for estimating oceanic flow

    Detta är en avhandling från Stockholm : Meteorologiska institutionen (MISU)

    Författare :Jenny A. U. Nilsson; Stockholms universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ocean monitoring techniques; Barotropic flow; Baroclinic flow; Hydraulic theory; Baltic Sea; Bahía de Concepción; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Oceanography; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Oceanografi; Oceanography; oceanografi;

    Sammanfattning : The aim of this thesis was to estimate and possibly quantify ocean flow by utilizing conventional and novel observational methods as well as model results. Motionally induced voltages, from a cable-based observational system in the Baltic Sea, were analysed to determine their utility for ocean monitoring. LÄS MER
