  1. 6. Children’s education and parents’ mortality – Do parents with highly educated children live longer?

    Master-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

    Författare :Pauline Bode; [2023]
    Nyckelord :Mortality inequalities; socioeconomic gradient in health; children’s education; socioeconomic status; SES; demography; Business and Economics;

    Sammanfattning : 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.

  3. 7. Wind Turbine Recovery Forecasting using Survival Analysis

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Anton Palets; [2023]
    Nyckelord :Survival analysis; Recovery Forecast; Wind Turbine; Availability Forecast; AFT model; Aalen s model; Cox regression; Cox Proportional Hazards; Variation Processes; Mathematics and Statistics;

    Sammanfattning : The goal of this thesis is to present a methodology for predicting time until recovery of failed wind turbines. The necessity is motivated by the potential for more accurate wind energy export forecasts. The current approach rests entirely on having an expert examine the turbine and produce a time estimate.

  4. 8. Identification of epigenetic biomarkers associated with the development of diabetic kidney disease in individuals with type 2 diabetes: a nested cohort study

    Master-uppsats, Lunds universitet/Socialmedicin och global hälsa

    Författare :Marian Paiva Marchiori; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction. Type 2 diabetes (T2D) is the most common type of diabetes, and it can cause complications such as diabetic kidney disease (DKD), the main cause of end-stage renal disease worldwide. There is an urgent need to develop new biomarkers that would improve DKD’s risk prediction in patients with T2D. LÄS MER
