1. 6. 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).

3. 7. Predicting the Impact of Supply Chain Disruptions Using Statistical Analysis and Machine Learning

   Master-uppsats, KTH/Matematisk statistik

   Författare :Hannes Andersson; John Sjöberg; [2023]
   Nyckelord :Supply chain disruption; SMOTE; feature engineering; machine learning; random forest; statistics; applied mathematics; Störning i försörjningskedja; maskininlärning; matematik; statistik;

   Sammanfattning : The dairy business is vulnerable to supply chain disruptions since large safety stocks to cover up losses are not always a viable option, therefore it is crucial to maintain a smooth supply chain to ensure stable delivery accuracies. Disruptions are unpredictable and hard to avoid in the supply chain, especially in cases where production errors cause lost production volume. LÄS MER

4. 8. Analyzing Survey Response Time and Response Rate for Colorectal Cancer Patients Using Logistic and Poisson Regression

   Kandidat-uppsats, KTH/Matematisk statistik

   Författare :Anna Möller; Martina Lagerros; [2023]
   Nyckelord :Applied Mathematics; Regression; Poisson Regression; Logistic Regression; Statistics; Cancer; Patients; Healthcare; Tillämpad Matematik; Statistik; Regression; Logistisk Regression; Poisson Regression; Cancer; Patientvård;

   Sammanfattning : Cancer is a highly prevalent disease worldwide, claiming hundreds of lives each year. In the field of cancer research, it is customary to conduct surveys in which patients are asked to self-report and assess their symptoms and overall health. LÄS MER

5. 9. A Predictive Analysis of Customer Churn

   Kandidat-uppsats, KTH/Matematisk statistik

   Författare :Olivia Eskils; Anna Backman; [2023]
   Nyckelord :Churn prediction; CRM; optimization; applied mathematics; machine learning; gradient boosting; random forest; logistic regression; insurance industry; Kundbortfall; CRM; optimering; tillämpad matematik; maskininlärning; gradient boosting; random forest; logistisk regression; försäkringsbranschen;

   Sammanfattning : Churn refers to the discontinuation of a contract; consequently, customer churn occurs when existing customers stop being customers. Predicting customer churn is a challenging task in customer retention, but with the advancements made in the field of artificial intelligence and machine learning, the feasibility to predict customer churn has increased.

7. 10. Analysing the Optimal Fund Selection and Allocation Structure of a Fund of Funds

   Master-uppsats, KTH/Matematik (Avd.)

   Författare :Idun Cederberg; Ida Cui; [2023]
   Nyckelord :Master Thesis; Financial Mathematics; Fund of Funds; Portfolio Optimization; Mean Variance Optimization; Masterexamensarbete; finansiell matematik; fond i fond; portföljoptimering; modern portföljteori;

   Sammanfattning : This thesis aims to investigate different types of optimization methods that can be used when optimizing fund of fund portfolios. Moreover, the thesis investigates which funds that should be included and what their respective portfolio weights should be, in order to outperform the Swedish SIX Portfolio Return Index. LÄS MER
