  1. 1. Avvikelseavkastning i samband med resultatöverraskningar på OMXS30 - En eventstudie

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Oskar Malmström; Johan Nordström; [2023]
    Nyckelord :avvikelseavkastning; eventstudie; kvartalsrapporter; OMXS30; resultatannonsering; resultatöverraskning;

    Sammanfattning : This thesis investigates if abnormal returns exist in connection to the release of quarterly reports depending on if the presented results overperform, underperform or are in line with the analysts expectations. An event study method is applied where the market model is used. LÄS MER

  3. 2. Developing an Advanced Method for Kinship from Ancient DNA Data

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Erkin Alacamli; [2023]
    Nyckelord :aDNA; ancient DNA; kinship estimation;

    Sammanfattning :  The analysis of kinship from ancient DNA (aDNA) data has the potential to provide insight into social structures of prehistoric societies. Kinship analysis is gaining popularity as optimised wet-lab methods allow for studies with sample sizes on the level of whole cemeteries. LÄS MER

  4. 3. Estimating the Impact of Website Changes on Conversion Rates

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen; Lunds universitet/Statistiska institutionen

  5. 4. Investigating the Estimation of the infection rate and the fraction of infections leading to death in epidemiological simulation

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

    Författare :Jakob Gölén; [2023]
    Nyckelord :Epidemics; Compartmental Models; Parameter Inference; Synthetic Bootstrap; Infection Rate;

    Sammanfattning : The main goal of this project is to investigate the behaviors of parameters used when modeling an epidemic. A stochastic SIHDRe model is used to simulate how an epidemic evolves over time. LÄS MER

  7. 5. Korttidsprognoser av Kalixälvens vattenflöde

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Mathilda Carlsson; [2023]
    Nyckelord :ARIMA; RecursiveAR; forgetting factor; sliding window; Kalman filter; short-term predictions; water flows; Mathematics and Statistics;

    Sammanfattning : The Kalix River, located in the northern part of Sweden, experiences a slowdown in water flow during cold winters. However, in spring, when snow and ice melt in the mountains, the water flow starts to increase. Towards the end of spring, there is usually a rapid and unpredictable surge in water flow known as the spring flood. LÄS MER
