  2. 1. Essays on Sample Surveys : Design and Estimation

    Author : Edgar Bueno; Per Gösta Andersson; Maria Giovanna Ranalli; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; GREG estimator; mixture distribution; probability proportional to size sampling; sampling algorithms; sampling design; sampling strategy; survey sampling; stratified sampling; Statistics; statistik;

    Abstract : Sampling is a core stage in every survey. A sampling design carefully elaborated may imply not only a more accurate estimation of the parameters of interest, but also a reduction in the required sample size in a study. In this thesis we consider two particular but connected subjects. READ MORE

  4. 2. On Methods for Real Time Sampling and Distributions in Sampling

    Author : Kadri Meister; Daniel Thorburn; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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; Mathematical Statistics; matematisk statistik;

    Abstract : 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. READ MORE

  5. 3. Cut-off and coordinated survey sampling

    Author : Kira Coder Gylling; Thomas Laitila; Nicklas Pettersson; Martin Axelson; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistik; Statistics;

    Abstract : The problem of estimation from a sample is well known and its solutions are the foundation for the sample surveys conducted at e.g. national statistical institutes. This dissertation looks at the estimation problem from the perspective of business survey methodology. READ MORE

  6. 4. Survey models for a vehicle speed survey

    Author : Annica Isaksson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; frame error; missing data; error model; optimum allocation; total error; MATHEMATICS; MATEMATIK;

    Abstract : The impact of some errors, associated with a road traffic survey, is examined. The survey aims at evaluating efforts to reduce the speeds on Swedish roads. It covers both state and urban roads, but we consider only the latter. From these roads, observational sites are selected by a three-stage sampling procedure. READ MORE

  7. 5. Emotional Reactions to Music : Prevalence and Contributing Factors

    Author : Simon Liljeström; Patrik N Juslin; Petri Toiviainen; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; music; emotion; personality; survey; experience sampling method; experiment; Psychology; Psykologi; Psychology; Psykologi;

    Abstract : People value music mainly for its abilities to induce emotions. Yet little is known about these experiences. The aim of this thesis was thus to investigate the nature and prevalence of emotional reactions to music, and what factors in the listener, the music, and the situation might contribute to such reactions.
