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

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

    Sammanfattning : 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. LÄS MER

  3. 22. 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

  4. 23. Some Contributions to Statistical Disclosure Control

    Författare :Michael Carlson; Mark Elliot; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Data dissemination; Data-swapping; Disclosure control; Poisson-inverse Gaussian; Risk-per-record; Superpopulation; Uniqueness; Mathematical statistics; Matematisk statistik; statistik; Statistics;

    Sammanfattning : An important issue associated with the release of statistical data, is the possibility of disclosing individual information about respondents. Statistical disclosure control (SDC), is the discipline that deals with methods of producing statistical data that are safe enough to be released while retaining its analytical value and also methods of assessing the disclosures risks.
