  4. 13. Statistical advancements in analyzing accelerometer-measured physical activity intensity

    Författare :Jonatan Fridolfsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; physical activity; accelerometry; cardiometabolic risk factors; cardiovascular disease; cardiorespiratory fitness; public health; statistics; multivariate; partial least squares; structural equation modelling;

    Sammanfattning : Physical activity (PA) is widely recognized as an important factor in preventing and treating cardiometabolic diseases and reducing mortality. Yet, the health implications of specific PA intensities and the intricate role of fitness in the relationship between PA and health remain less clear. LÄS MER

  5. 14. Statistical Methods for Taxon Classification and Bird Migration Phenology

    Författare :Måns Karlsson; Ola Hössjer; Jonas Knape; Benjamin Bolker; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Classification; quantile regression; phenology; statistical ornithology; L-functionals; set-valued classification; species identification; statistical ecology; multispecies modelling; matematisk statistik; Mathematical Statistics;

    Sammanfattning : The connection between ecology and statistics is deep. Methodological advancement in statistics open up new possibilities to understand the distribution of life on earth, and research questions in ecology cause new statistical methods to be developed. LÄS MER

  7. 15. Physico-chemical characteristics and quantitative structure-activity relationships of PCBs

    Författare :Patrik Andersson; Stephen Safe; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polychlorinated biphenyls; PCBs; physico-chemical properties; statistical design; multivariate; PCA; PLS; biomagnification; BMF; bioassay; CYP1A; SAR; QSAR; REPs; risk assessment; Chemistry; Kemi; Chemistry; Kemi;

    Sammanfattning : The polychlorinated biphenyls (PCBs) comprise a group of 209 congeners varying in the number of chlorine atoms and substitution patterns. These compounds tend to be biomagnified in foodwebs and have been shown to induce an array of effects in exposed organisms. LÄS MER
