1. Multi-state and Time-varying Covariate Survival Models for Multiple Knee Contractures in People with Cerebral Palsy
Kandidat-uppsats, Lunds universitet/Matematisk statistikSammanfattning : Cerebral palsy is an umbrella term for a group of neurological disorders, affecting motor function, movement and posture. Contractures, restrictions in the range of motion of joints, are a common problem affecting people living with cerebral palsy. LÄS MER
2. A Causal Analysis of Cat Bond Markets
D-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomiSammanfattning : This work is a contribution to the causal analysis of the catastrophe bond market, which has generated high excess returns over the last two decades. Since these excess returns remain partially unexplainable and the interest in catastrophe bonds is increasing, the causal study of the factors affecting their premiums is of high relevance. LÄS MER
3. A survival analysis on endurance tests of chainsaws and power cutter components at Husqvarna Group AB
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : Due to the steadily growing world chainsaw market and the market’s relative competitiveness, high performing chainsaws are important for Husqvarna Group AB to remain competitive. In the development phase a large number of endurance tests are run to evaluate the product’s performance. LÄS MER
4. Channel Equalization Using Machine Learning for Underwater Acoustic Communications
Master-uppsats, Linköpings universitet/KommunikationssystemSammanfattning : Wireless underwater acoustic (UWA) communications is a developing field with various applications. The underwater acoustic communication channel is very special and its behavior is environment-dependent. The UWA channel is characterized by low available bandwidth, and severe motion-introduced Doppler effect compared to wireless radio communication. LÄS MER
5. Sales Modeling and Local Factor Decomposition for Optimal Investment Decisions in MMM: A Monte Carlo Simulation Study
D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomiSammanfattning : Media Mix Models (MMM) are used to understand drivers behind key performance indicators and to measure the effectiveness of media channels. The key metric to report causal impacts of media investments on sales is return on investment (ROI). The shape of ROI-curves crucially impacts optimal allocation. LÄS MER
