1. Biological Age and Risk of Developing Alzheimer's Disease and Related Dementias
Master-uppsats, KTH/ProteinvetenskapSammanfattning : Biologisk ålder (BA) har nyligen fått ökad uppmärksamhet att fördjupa förståelsen kring åldersrelaterade sjukdomar och dess behandlingar, eftersom åldersrelaterade förändringar utgör en grundläggande gemensam nämnare för dessa tillstånd. Medan kronologisk ålder (CA) mäts i år, kan biologisk ålder (BA) mätas på många olika sätt. LÄS MER
2. Competition and Physician Turnover: Evidence from Swedish Primary Care Units
Master-uppsats, Göteborgs universitet/Graduate SchoolSammanfattning : The Swedish government has over the years implemented several reforms to improve health care system and ensure continuity of care. One of the reforms, The Act on Free Choice, was implemented between 2007 and 2010 providing patients a free choice to choose a provider and private providers to freely enter the market; thereby, increasing the competition among providers.

3. Children’s education and parents’ mortality – Do parents with highly educated children live longer?
Master-uppsats, Lunds universitet/Ekonomisk-historiska institutionenSammanfattning : While there exists a large literature on mortality inequalities by an individual’s level of education and other socioeconomic characteristics this thesis looks at the relationship between the children’s level of education and parents’ mortality, which has been relatively less studied. I use longitudinal data from the Survey of Health, Ageing and Retirement in Europe (SHARE) for the years 2004-2017 and conduct Cox proportional hazard regressions to assess how children’s level of education affects parents’ mortality risks.

4. En överlevnadsstudie av återfallsbrottslighet i Sverige 2010-2020
Kandidat-uppsats, Stockholms universitet/Statistiska institutionenSammanfattning : Återfallsbrottslighet är ett väl beforskat ämne inom såväl kriminologisk som statistik forskning. Däremot är underlaget begränsat och dåligt uppdaterat på svenska material. Denna studie har med överlevnadsanalys undersökt tid till återfall i Sverige över tidsperioden 2010 till 2020. LÄS MER
5. Deep Learning Approach for Time- to-Event Modeling of Credit Risk
Master-uppsats, KTH/Matematisk statistikSammanfattning : This thesis explores how survival analysis models performs for default risk prediction of small-to-medium sized enterprises (SME) and investigates when survival analysis models are preferable to use. This is examined by comparing the performance of three deep learning models in a survival analysis setting, a traditional survival analysis model Cox Proportional Hazards, and a traditional credit risk model logistic regression.
