  4. 3. Multivariate Aspects of Phylogenetic Comparative Methods

    Författare :Krzysztof Bartoszek; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; General Linear Model; Ornstein-Uhlenbeck process; Multivariate phylogenetic comparative method; Evolutionary model; Adaptation; Optimality; Measurement error; Regression; Adaptation; Major-axis regression; Reduced major-axis regression; Structural equation; Allometry; Phylogenetic inertia; Allometry;

    Sammanfattning : his thesis concerns multivariate phylogenetic comparative methods. We investigate two aspects of them. The first is the bias caused by measurement error in regression studies of comparative data. We calculate the formula for the bias and show how to correct for it. LÄS MER

  5. 4. Bayesian Inference in Structural Second-Price Auctions

    Författare :Bertil Wegmann; Mattias Villani; Samita Sareen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Asymmetry; Bid function approximation; Common values; Gamma model; Gaussian model; Markov Chain Monte Carlo; Private values; Variable selection; Internet auctions; Statistics; Statistik; Statistics; statistik;

    Sammanfattning : The aim of this thesis is to develop efficient and practically useful Bayesian methods for statistical inference in structural second-price auctions. The models are applied to a carefully collected coin auction dataset with bids and auction-specific characteristics from one thousand Internet auctions on eBay. LÄS MER

  7. 5. A trust-privacy model of customers' willingness to be profiled and to transact online : theoretical model and empirical estimation

    Författare :Atanu Nath; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Industrial Marketing; Industriell marknadsföring;

    Sammanfattning : Privacy concerns are cited to be on the rise due to intense personalization efforts by online firms. Alongside, trust placed in stores has been identified as a key component behind consumer willingness to transact online. LÄS MER
