  1. 1. Effects of management and plant traits on tree-related microhabitats in second-growth stands of the Białowieża Forest

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Weronika Mysiak; [2022]
    Nyckelord :tree-related microhabitats; TreMs; Białowieża Forest; post-Century stands; second-growth forest;

    Sammanfattning : The study presents research conducted on Tree-related Microhabitats (TreM) in managed stands and nearly unmanaged stands in the Białowieża Forest (BF). A TreM is an above-ground structure that creates substrate, site or place for forest-dwelling species, and could be an important tool for assessing the level of biodiversity. LÄS MER

  3. 2. Vad kan svenska skolbarn i årskurs 2, 3 och 4 om affix? En pilotstudie om morfologisk kunskap

    Magister-uppsats, Lunds universitet/Logopedi, foniatri och audiologi

    Författare :Angela Tamakloe; Kristina Hallenbrant; [2022]
    Nyckelord :morphological knowledge; word comprehension; communication skills; SES; multilingualism; Medicine and Health Sciences;

    Sammanfattning : Syfte: Den här pilotstudien hade syftet att undersöka svårighetsgraden av ett urval affix inför en kommande interventionsstudie (huvudstudie) och därmed få en ökad kunskap om barns förståelse för morfem. Studien syftade även till att undersöka samband mellan morfologisk kunskap och ordförståelse samt lärarskattning av kommunikationsförmåga. LÄS MER

  4. 3. Bid Forecasting in Public Procurement

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Karim Stiti; Shih Jung Yape; [2019]
    Nyckelord :Bidding in public procurement; Count data regression; Economically most advantageous tenders; Lowest price tenders; Machine learning; Multiple linear regression; Nonparametric bootstrap; Position performance coefficient; Sealed-bid auctions; Stochastic dominance; Support vector regression.; Budgivningsmodeller I offentliga upphandlingar; Ekonomiskt mest fördelaktiga anbud; Förseglade auktioner; Lägsta-pris anbud; Maskininlärning; Multipel linjär regression.;

    Sammanfattning : Public procurement amounts to a significant part of Sweden's GDP. Nevertheless, it is an overlooked sector characterized by low digitization and inefficient competition where bids are not submitted based on proper mathematical tools. LÄS MER

  5. 4. Fisher's Randomization Test versus Neyman's Average Treatment Test

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Kajsa-Lotta Georgii Hellberg; Andreas Estmark; [2019]
    Nyckelord :Nonparametric; Parametric; Monte Carlo Approximation; Inference;

    Sammanfattning : The following essay describes and compares Fisher's Randomization Test and Neyman's average treatment test, with the intention of concluding an easily understood blueprint for the comprehension of the practical execution of the tests and the conditions surrounding them. Focus will also be directed towards the tests' different implications on statistical inference and how the design of a study in relation to assumptions affects the external validity of the results.

  7. 5. Nonparametric Asset Pricing with Conditioning Information

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Christoffer Sjöström; Dominik Schmitz; [2018]
    Nyckelord :Conditional Asset Pricing; Nonparametric SDF; Nonlinear Pricing Kernel; Stochastic Discount Factor; Time-varying Betas;

    Sammanfattning : This study sets out to be the very first in introducing the notion of a nonlinear pricing kernel in conditional asset pricing for the Swedish equity market. By implementing a flexible nonparametric methodology, we are able to conduct tests that are completely free from functional form specifications of time-varying betas, risk premia and the stochastic discount factor.
