  2. 1. Strategies for assessing health risks from two occupational cohorts within the domain of northern Sweden

    Author : Ove Björ; Tohr Nilsson; Håkan Jonsson; Lena Damber; Per Gustavsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cohort; mortality; incidence; risk; rate; cancer; cerebrovascular diseases; exposure; occupational; mining; industry; worker; Poisson regression; Cox regression; SMR; causal inference; G-estimation; Occupational and Environmental Medicine; arbets- och miljömedicin; epidemiologi; Epidemiology;

    Abstract : Background: Studies based on a cohort design requires access to both subject-specific and period-specific information. In order to conduct an occupational cohort study, access to exposure information and the possibility and permission to link information on outcomes from other registers are generally necessary.

  6. 4. Order restricted inference over countable preordered sets. Statistical aspects of neutron detection

    Author : Vladimir Pastukhov; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Constrained inference; Isotonic regression; Density estimation; Grenander estimator; Limit distribution; Neutron detection;

    Abstract : This thesis consists of four papers. In the first paper, we study the isotonic regression estimator over a general countable preordered set. We obtain the limiting distribution of the estimator and study its properties. Also, it is shown that the isotonisation preserves the rate of convergence of the underlying estimator. READ MORE

  7. 5. Some Contributions to Statistical Disclosure Control

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

    Abstract : 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.
