  1. 1. A Comparative Investigation of Classical Random and Quantum Walks in Terms of Algorithms, Implementation, and Characteristics

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Naoki Moriya; [2024]
    Nyckelord :Qunatum computing; quantum walk;

    Sammanfattning : In recent years, there has been a significant development in high performance computing, driven by advances in hardware and software technology. The performance of the computers to the present has improved in accordance with Moore’s law, on the other hand, it seems to be reaching the limits in the near future. LÄS MER

  3. 2. Spatio-temporal analysis of COVID-19 in Västra Götaland, Sweden

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Natalia Andreeva; [2023-08-23]
    Nyckelord :;

    Sammanfattning : Spatio-temporal analysis of COVID-19 data with the two different statistical approaches is the main objective of this thesis. The first classical approach, the Endemic-Epidemic framework (Held et al., 2005) is a class of multivariate time-series models for the incidence counts, obtained from the surveillance systems.

  4. 3. CROSS-SECTIONAL AND TIME SERIES MOMENTUM RETURNS EVIDENCE FROM THE SWEDISH STOCK MARKET

    Kandidat-uppsats, KTH/Matematisk statistik

    Författare :Mahsa Badakhsh; [2023]
    Nyckelord :cross-sectional momentum; time-series momentum; market efficiency; random walk; ex-ante volatility; cross-sectional momentum; time-series momentum; marknadseffektivitet; random walk; ex-ante volatilitet;

    Sammanfattning : The study investigates the presence of the momentum effect in the Swedish stock market by utilizing both cross-sectional introduced by Jegadeesh and Titman (1993) and time-series momentum introduced by Moskowtozt et al. (2011). The period of analysis is between 1998 to 2022. LÄS MER

  5. 4. Does the Level of Swedish Economic Policy Uncertainty Help Forecast Excess Returns on the Swedish Stock Market?

    Master-uppsats, Uppsala universitet/Företagsekonomiska institutionen

    Författare :Gustav Jacobsson; Oscar Klersell; [2023]
    Nyckelord :Economic Policy Uncertainty EPU ; Excess stock returns; Out-of-sample forecasting; Random walk; Sweden;

    Sammanfattning : This thesis examines whether the level of Swedish economic policy uncertainty (EPU) can predict excess returns on the Swedish stock market. We run out-of-sample forecasting using an EPU-based predictive model constructed with the official Swedish EPU index developed by Armelius et al. (2017). LÄS MER
