1. 21. Robust Statistical Jump Models with Feature Selection

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Jonatan Persson; [2023]
   Nyckelord :Clustering; Jump; Feature selection; Robust; Mathematics and Statistics;

   Sammanfattning : A large area in statistics and machine learning is cluster analysis. This field of research concerns the design of algorithms that allow computers to automatically categorize a set of observations into different groups in a reasonable way, without any prior information about which observations belongs to which group.

3. 22. Assessment and evaluation of heterogeneity in data from immune infiltration spatial niches in lung cancer

   Kandidat-uppsats, Lunds universitet/Matematisk statistik

   Författare :Mahta Keivani Najafabadi; [2023]
   Nyckelord :Mathematics and Statistics;

   Sammanfattning : The protein biomarker expressions in three types of sampled immune INFILTration spatial niches in lung cancer tissue were measured using the new technology Digital Spatial Profiler (DSP). The three types of immune INFILTration that were observed in lung tumors were STROMA identified as immune cells separate from tumor cells, Tertiary lymphoid structures (TLS) identified as dense structures of organized immune cells and finally Infiltraterate where immune cells dispersed among and in direct contact with tumor cells (INFILT).

4. 23. Exploration of using Twitter data to predict Swedish political opinion polls with neural networks

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Alexander Gren; Klara Lundgren; [2023]
   Nyckelord :Mathematics and Statistics;

   Sammanfattning : This thesis aims to explore the possibility of using deep learning techniques to mine opinions on Twitter, with the objective to predict the political opinion distribution in Sweden. Different methods of gathering and annotating training data are evaluated to achieve accurate and reliable predictions. LÄS MER

7. 25. Exchange Rate and Equity Market Dependence under Shifts in Volatility Expectations

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Vilhelm Samuelsson; [2023]
   Nyckelord :Exchange rates; Equity markets; Volatility; ARMA-GARCH; Copula; Exchange rate determination; Safe-haven; Portfolio rebalancing; Return chasing; Mathematics and Statistics;

   Sammanfattning : Exchange rate movements have important implications for both policy makers and investors, as they can have large effects on the real economy and the return on investments. Lately, their relation to capital flows have attracted growing interest due to the failure of macroeconomic fundamentals to explain them. LÄS MER
