  1. 1. Biased While Betting on Bernie? A cross-sectional and panel data analysis of prediction error in U.S. election prediction markets from 2015 to 2020

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Daniel Evans; [2021]
    Nyckelord :prediction markets; political science; behavioral economics; U.S. elections; bias;

    Sammanfattning : A consensus seems to have emerged that political prediction markets can lose predictive power when certain efficiency criteria are not met. With a cross-sectional dataset of 570 prediction markets about U.S. elections and a panel dataset with 6,465 days of trading from PredictIt. LÄS MER

  2. 2. A small sample study of some sandwich estimators to handle heteroscedasticity

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Viking Westman; [2021]
    Nyckelord :;

    Sammanfattning : This simulation study sets out to investigate Heteroscedasticity-Consistent Covariance Matrix Estimation using the sandwich method in relatively small sample sizes. The different estimators are evaluated on how accurately they assign confidence intervals around a fixed, true coefficient, in the presence of random sampling and both homo- and heteroscedasticity.

  3. 3. Deep learning exotic derivatives

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Gunnlaugur Geirsson; [2021]
    Nyckelord :deep learning; neural networks; derivative pricing; automatic differentiation; Monte Carlo; transfer learning; structured products; risk sensitivities; valuation; autocalls;

    Sammanfattning : Monte Carlo methods in derivative pricing are computationally expensive, in particular for evaluating models partial derivatives with regard to inputs. This research proposes the use of deep learning to approximate such valuation models for highly exotic derivatives, using automatic differentiation to evaluate input sensitivities. LÄS MER

  4. 4. Uppskattning av personantal med hjälp av Wi-Fi

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Kassem Abou Nawfal; Adam Adolfsson; [2021]
    Nyckelord :Personantal; persontäthet; brandskydd; utrymning; Wi-Fi; WLAN; Occupant load; occupant density; fire safety; evacuation; Technology and Engineering;

    Sammanfattning : Knowledge of the occupant load is an important parameter during the fire evacuation design in buildings. Current regulations regarding occupant load does not consider variation in scenarios with great uncertainties. By taking variation of the occupant load into account, the risk levels can be reduced, and a safe evacuation can take place. LÄS MER

  5. 5. Geo-temporal Online Analysis of Traffic Rule Violations

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Adam Davidsson; Dyako Fatih; Simon Larsson; Jesper Naarttijärvi; Daniel Nilsson; Marcus Svensson; [2020-10-30]
    Nyckelord :Traffic rule violations; Risk estimation; Privacy preservation; Computer vision; Deep learning neural net;

    Sammanfattning : Due to inattention and not complying with traffic regulations, human error accounts forroughly 94% of all traffic accidents. To counter this, the need to develop systems that canidentify traffic rule violations and calculate the risk of collisions. The information reportedcan then be used to implement preventive measures.
