1. 16. Stock market analysis with a Markovian approach: Properties and prediction of OMXS30

   Kandidat-uppsats, KTH/Matematisk statistik

   Författare :Max Aronsson; Anna Folkesson; [2023]
   Nyckelord :Markov chain; OMXS30; Markov chain properties; voting ensemble model; markovkedja; OMXS30; egenskaper hos markovkedjor; ensemble-modell;

   Sammanfattning : This paper investigates how Markov chain modelling can be applied to the Swedish stock index OMXS30. The investigation is two-fold. Firstly, a Markov chain is based on index data from recent years, where properties such as transition matrix, stationary distribution and hitting time are studied. LÄS MER

3. 17. Restaurant Daily Revenue Prediction : Utilizing Synthetic Time Series Data for Improved Model Performance

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

   Författare :Stella Jarlöv; Anton Svensson Dahl; [2023]
   Nyckelord :demand forecasting; data augmentation; time series data; machine learning; restaurant industry; generative adversarial networks; TimeGAN; XGBoost;

   Sammanfattning : This study aims to enhance the accuracy of a demand forecasting model, XGBoost, by incorporating synthetic multivariate restaurant time series data during the training process. The research addresses the limited availability of training data by generating synthetic data using TimeGAN, a generative adversarial deep neural network tailored for time series data. LÄS MER

4. 18. Användning av logistisk regression för att prediktera utfallet i snooker

   Kandidat-uppsats, Stockholms universitet/Matematiska institutionen

   Författare :Leo G. Levenius; [2023]
   Nyckelord :Logistic regression; prediction; snooker; Logistisk regression; prediktion; snooker;

   Sammanfattning : Syftet med det här arbetet är att undersöka hur väl logistisk regression kan användas för att prediktera vinnaren i en snookermatch. Detta görs med hjälp av statistik över spelarna samt resultat från tidigare matcher och turneringar. LÄS MER

5. 19. 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

7. 20. ASSESSING PREDICTION CONDITIONS ANDSEQUENTIAL CLASSIFICATION IN ICU SEPSISPREDICTION

   Master-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Petter Lind; [2023]
   Nyckelord :Sepsis Prediction; Sequential Prediction; Conditional Predictions; XGBoost;

   Sammanfattning : Patients admitted to intensive care units (ICUs) often have a higher risk of sepsis due to weakened immune systems. Early sepsis diagnosis is crucial for timely treatment, emphasizing the need to improve the predictive capabilities of sepsis prediction models. LÄS MER
