  1. 1. Investigating the Estimation of the infection rate and the fraction of infections leading to death in epidemiological simulation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Jakob Gölén; [2023]
    Nyckelord :Epidemics; Compartmental Models; Parameter Inference; Synthetic Bootstrap; Infection Rate;

    Sammanfattning : The main goal of this project is to investigate the behaviors of parameters used when modeling an epidemic. A stochastic SIHDRe model is used to simulate how an epidemic evolves over time. LÄS MER

  3. 2. Application of Bootstrap in Approximate Bayesian Computation (ABC)

    Master-uppsats, Uppsala universitet/Statistik, AI och data science

    Författare :Ellinor Nyman; [2023]
    Nyckelord :ABC; Bootstrap; Computer intensive methods; Bayesian statistics; Linear regression;

    Sammanfattning : The ABC algorithm is a Bayesian method which simulates samples from the posterior distribution. In this thesis, the method is applied on both synthetic and observed data of a regression model. Under normal error distribution a conjugate prior and the likelihood function are used in the algorithm. LÄS MER

  4. 3. Modeling the yield curve in conjunction with the FX spots

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Philip Lundqvist; [2022]
    Nyckelord :Yield Curve; FX spots; Bootstrap; Hull-White; Simulation; Calibration;

    Sammanfattning : Interest rates and foreign exchange spots are widely used within financial products. It is important to understand the risk arising from products that depend on interest rates and/or foreign exchange spots. LÄS MER

  5. 4. Uncertainty Analysis of Long Term Correction Methods for Annual Average Winds

    Master-uppsats, Institutionen för fysik

    Nyckelord :Uncertainty; Long-term-correction; Measure-Correlate-Predict; Sector-Bin; Synthetic time series; Reference dataset; Weather observation stations; WRF; MERRA; QuikSCAT; NCEP FNL; Bootstrap; sampling; North Sea.; Osäkerhet; Measure-Correlate-Predict; årsmedelvind; Sektor-Bin; Syntetiska tidsserier; referensdataset; väderobservationsstationer; WRF; MERRA; QuikSCAT; NCEP FNL; Bootstrap; sampling; Nordsjön.;

    Sammanfattning : For the construction of a wind farm, one needs to assess the wind resources of the considered site location. Using reference time series from numerical weather prediction models, global assimilation databases or observations close to the area considered, the on-site measured wind speeds and wind directions are corrected in order to represent the actual long-term wind conditions.
