  3. 17. Optimal Subsampling Designs Under Measurement Constraints

    Författare :Henrik Imberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; inverse probability weighting; unequal probability sampling; optimal design; active sampling; M-estimation;

    Sammanfattning : We consider the problem of optimal subsample selection in an experiment setting where observing, or utilising, the full dataset for statistical analysis is practically unfeasible. This may be due to, e.g., computational, economic, or even ethical cost-constraints. LÄS MER

  4. 18. On predictions, measurement, and causal inference : Essays on statistical correlations and statistical applications in labor market economics and criminology

    Sammanfattning : This thesis consists of five papers covering a broad range of statistical themes, from prediction via correlation measures to causal inference.Paper I uses a nationally representative survey of separated Swedish women to examine whether men who strive to control their partners during their relationships are more likely to stalk or assault their ex-partners after separation.

  7. 20. Geometrical and dimensional Measurement Planning : - a systematic and holistic approach

    Författare :Richard Lindqvist; Lars Mattsson; Martin Helgoson; KTH; []
    Nyckelord :Geometrical; dimensional; measurement planning; controllability; GMCP; quality assurance matrix and methodology; QAM; critical key characteristic;

    Sammanfattning : För att försäkra sig om den slutliga kvaliteten på maskinbearbetade komponenter måste tillverkande företag mäta och verifiera de geometriska och dimensionella egenskaperna på komponenter innan dem skickas vidare nedströms till den mer värdeskapande monteringen. Det är idag vanligt att den geometriska och dimensionella mätningen och verifieringen uppstår varje gång då en maskin ställs om, när man startar om eller startar upp en ny produktionslina eller då en produktionsprocess ändras.
