  1. 21. A study on the relation between VIX, S&P500 and the CDX-index

    Kandidat-uppsats, Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Författare :Niklas Rugås; Alexander Winberg; [2015-02-26]
    Nyckelord :Implied volatility; Credit default swaps; Credit spreads; Stock index; Correlation;

    Sammanfattning : In this thesis we investigate the relationship between the VIX-index, CDX NA IG and S&P500. Our goal is to study how well the market volatility (traded in VIX) can be explained by stock prices(S&P500) and credit indices (CDX NA IG) The VIX-index is a measure of implied volatility in the S&P500 and is often referred to as a fear index. CDX.NA. LÄS MER

  7. 25. Evaluating habitat suitability and spectral heterogeneity models to predict weed species presence

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Christina Fotiou; [2014]
    Nyckelord :GARP; herbicide resistant weeds; climate change; spatial heterogeneity; habitat; regression; NDVI; Physical Geography and Ecosystem Analysis; GIS; Earth and Environmental Sciences;

    Sammanfattning : The aim of this study is to analyze whether the presence of weed species resistant to herbicides is related to landscape heterogeneity and environmental variables. C3 and C4 weed species, such as Chenopodium album, Conyza canadensis, Amaranthus retroflexus, Papaver rhoeas, Sorghum halepense, Echinochloa crus-galli and Lolium rigidum, are studied in two differing bioclimatic countries, Greece and Germany.
