  1. 6. On Degree Variance in Random Graphs

    Författare :Jan Hagberg; Ove Frank; Tom A.B. Snijders; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Degree Sequences; Uniform Random Graphs; Bernoulli Graphs; Degree Moments; Degree Statistics; Degree Variance; Gamma Approximation; Centrality Testing; Integer Sequences; Statistics; Statistik;

    Sammanfattning : This thesis is concerned with degree moments and degree variance in random graphs. The degree of vertex i in a graph is the number of edges incident to vertex i.In the first paper, degree moments and functions of degree moments are investigated for three random graph models.

  3. 7. Some properties of measures of disagreement and disorder in paired ordinal data

    Författare :Hans Högberg; Elisabeth Svensson; Sture Holm; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; agreement; augmented ranks; categorical data; disorder; jackknife; paired ordinal data; rating scales; sample size; sampling distribution; simulation; U-statistics; variance; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Statistics; Statistik; Statistics; Statistik;

    Sammanfattning : The measures studied in this thesis were a measure of disorder, D, and a measure of the individual part of the disagreement, the measure of relative rank variance, RV, proposed by Svensson in 1993. The measure of disorder is a useful measure of order consistency in paired assessments of scales with a different number of possible values. LÄS MER

  4. 8. 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.
