1. Decision Trees for Classification of Repeated Measurements
University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakultetenAbstract : Classification of data from repeated measurements is useful in various disciplines, for example that of medicine. This thesis explores how classification trees (CART) can be used for classifying repeated measures data. READ MORE

2. Predictive Modeling and Statistical Inference for CTA returns : A Hidden Markov Approach with Sparse Logistic Regression
University essay from Umeå universitet/Institutionen för matematik och matematisk statistikAbstract : This thesis focuses on predicting trends in Commodity Trading Advisors (CTAs), also known as trend-following hedge funds. The paper applies a Hidden Markov Model (HMM) for classifying trends. Additionally, by incorporating additional features, a regularized logistic regression model is used to enhance prediction capability. READ MORE

3. Bootstrapping methods for assessing causality in survival analysis: A case study on major adverse cardiovascular events
University essay from Lunds universitet/Matematisk statistikAbstract : The combination of graphical models with Aalen's additive hazards model, resulting in a model known as dynamical path analysis, permits assessing the effects of different variables on times until an event and decomposing these total effects into direct and indirect effects. This thesis proposes novel bootstrapping methods designed for left-truncated right-censored data, conditional on covariates within the framework of Aalen's additive hazards model, in order to obtain confidence intervals for the estimates.

4. Computational prediction of cell-cell interactions in the brain-tumour microenvironment
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Glioblastoma is the fastest-growing, and the most common malignant brain tumour in adults. It is normally treated with surgery and radio- or chemotherapy, but the approximate life expectancy is of 15 months with a high probability of cancer recurring. Therefore, there is a need for decreasing its severity. READ MORE

5. Evaluating Bag Of Little Bootstraps On Logistic Regression With Unbalanced Data
University essay from Uppsala universitet/Statistiska institutionenAbstract : The Bag of Little Bootstraps (BLB) was introduced to make the bootstrap method more computationally efficient when used on massive data samples. Since its introduction, a broad spectrum of research on the application of the BLB has been made. READ MORE
