1. 1. Does industry survey data improve GDP forecasting?

   Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionen

   Författare :Oscar Andersson; Ludvig Fornstedt; [2024-03-06]
   Nyckelord :Bayesian; BVAR; Forecasting; GDP; survey data;

   Sammanfattning : This study assesses the integration of industry survey data into Bayesian Vector Auto Regressive (BVAR) models for GDP forecasting in Sweden. Analyzing a combination of macro economic indicators, CPI and unemployment rates, with survey data from NIER, it explores the effects of different variable combinations on the forecasting ability of different models.

3. 2. Fotbollsmålvakters antecipation under straffläggning : Betydelsen av explicit kontextuell information

   Kandidat-uppsats, Högskolan i Halmstad/Akademin för hälsa och välfärd

   Författare :Hampus Abrahamsson; [2024]
   Nyckelord :Antecipation; Fotballgoalkeepers; Bayesian theory; explicit contextual prior information; kinematic information; Antecipation; Fotbollsmålvakter; Bayesiansk teori; explicit kontextuell förhandsinformation; kinematisk information;

   Sammanfattning : Syftet med studien var att studera effekten av explicit kontextuell förhandsinformation på olika reliabilitetsnivåer hos fotbollsmålvakters förmåga att rädda straffar. Hypotesen som sattes utgick från att det skulle finnas en effekt av kontextuell förhandsinformation under förhållandet med stark handlingstendens, samtidigt skulle det inte finnas någon effekt av kontextuell förhandsinformation på målvakters förmåga vid förhållandet av svag handlingstendens.

   Nyckelord :Uncertainty quantification; Deep learning; Breast cancer classification; Trustworthy AI; Point-of-care ultrasound; Mathematics and Statistics;

   Sammanfattning : Breast cancer is the most common type of cancer worldwide with an estimate of 2.3 million new cases in 2020, and the number one cause of cancer-related deaths in women. LÄS MER

5. 4. Modelling the Exchange Rate: Evidence from the Impacts of Quantitative Easing in Sweden

   D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

   Författare :Anny Eklund; Markus Sallkvist; [2024]
   Nyckelord :Quantitative easing; Exchange rate; Bayesian VAR model; Small open economy; Triangular factorisation;

   Sammanfattning : Quantitative easing, the unconventional monetary policy measure used by many central banks to combat low inflation when interest rates are at the lower bound, has shown to be an effective tool for depreciating the domestic currency. Although the exchange rate is of particular importance in a small open economy as it directly impacts inflation dynamics,trade competitiveness and plays a substantial role in shaping monetary policy, few papers have investigated how the depreciating effect of QE to the exchange rate works.

7. 5. Regularization Methods and High Dimensional Data: A Comparative Study Based on Frequentist and Bayesian Methods

   Kandidat-uppsats, Lunds universitet/Statistiska institutionen

   Författare :Markus Gerholm; Johan Sörstadius; [2024]
   Nyckelord :Linear regression; high dimensional data; regularization; Bayesian methods; Mathematics and Statistics;

   Sammanfattning : As the amount of high dimensional data becomes increasingly accessible and common, the need for reliable methods to combat problems such as overfitting and multicollinearity increases. Models need to be able to manage large data sets where predictor variables often outnumber the amount of observations. LÄS MER
