1. 1. Evaluating a LSTM model for bankruptcy prediction with feature selection

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Emma Carlsson; [2023]
   Keywords : Feature selection; Bankruptcy prediction; Neural networks; LSTM; Chi-squared; t-test; Stepwise regression; Lasso regression; Random forest;

   Abstract : Bankruptcy prediction is an important research topic. The cost of incorrect decision making in companies and financial institutions can be great and could affect large parts of society. But while it is indeed a major research area, there are few studies which consider the effects of feature selection. READ MORE

3. 2. Forecasting Football Corner Odds: Statistical Modelling, Betting Strategies and Assessing Market Efficiency

   University essay from Lunds universitet/Matematisk statistik

   Author : Gustav Pålsson; Marcus Laurens; [2023]
   Keywords : Mathematics and Statistics;

   Abstract : Statistical modelling could be included in a betting strategy where the value of a bet is assessed by comparing model predictions and market odds. This thesis presents several models based on statistical learning methods for predicting the total number of corners in a football match. READ MORE

4. 3. Investigating maintenance costs using response feature analysis

   University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

   Author : Linus Hansson; [2022]
   Keywords : Response feature analysis; longitudinal data; maintenance costs; Response feature analysis; longitudinell data; underhållskostnader;

   Abstract : Svenska Kraftnät (Svk) is responsible for ensuring that Sweden has a safe, sustainable, and cost-effective transmission system for electricity. In an effort to reduce costs, Svk has participated in a study where it has been determined that there are mostly costs for common facilities that stand out cost-wise. READ MORE

5. 4. Evaluating Risk Factors with Regression : A Review and Simulation Study of Current Practices

   University essay from Uppsala universitet/Statistiska institutionen

   Author : Ragna Reinhammar; [2022]
   Keywords : ;

   Abstract : The term ”risk factor” is used synonymously with both predictor and causal factor, and causal aims of explanatory analyses are rarely stated explicitly. Consequently, the concepts of explaining and predicting are conflated in risk factor research. READ MORE

6. 5. Automatic Development of Pharmacokinetic Structural Models

   University essay from Uppsala universitet/Institutionen för farmaci

   Author : Alzahra Hamdan; [2022]
   Keywords : pharmacometrics; non-linear mixed effects; modelling; pharmacokinetics; NONMEM; automation; exhaustive algorithm; stepwise algorithm; structural models; inter-individual variability; residual error models; model selection;

   Abstract : Introduction: The current development strategy of population pharmacokinetic models is a complex and iterative process that is manually performed by modellers. Such a strategy is time-demanding, subjective, and dependent on the modellers’ experience. READ MORE
