  1. 6. Application of Bootstrap in Approximate Bayesian Computation (ABC)

    University essay from Uppsala universitet/Statistik, AI och data science

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

    Abstract : 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. READ MORE

  3. 7. Spatial modeling with INLA for analysis of unequal care in Skåne

    University essay from Lunds universitet/Matematisk statistik

    Author : Julia Wierzchoslawska; [2023]
    Keywords : Mathematics and Statistics;

    Abstract : The objective of this thesis is to extend on a previous analysis of health care accessibility for patients diagnosed with a chronic disease in Region Skåne. The previous analysis resulted in a logistic mixed effects model having municipality as a random effect and age as a first-degree spline-function. READ MORE

  4. 8. Dynamic Covariance Modelling Using Generalised Wishart Processes

    University essay from Lunds universitet/Matematisk statistik

    Author : Fredrik Nilsson; [2023]
    Keywords : Covariance matrix; generalised Wishart process; Bayesian inference; Markov chain Monte Carlo; Hamiltonian Monte Carlo; Mathematics and Statistics;

    Abstract : Modern portfolio theory was pioneered by Markowitz who formulated the mean-variance problem, without which any discussion on quantitative approaches to portfolio selection would be incomplete. The framework boils down to finding the expected return $\mu$ and covariance $\Sigma$, after which the solution is proportional to $\Sigma^{-1}\mu$. READ MORE

  5. 9. Probabilistic settlement analysis for embankments using preloading without surcharge

    University essay from KTH/Jord- och bergmekanik

    Author : Karl Escher; [2022]
    Keywords : Bayesian statistics; uncertainty; geotechnical risk evaluation; preloading; consolidation; embankments; ground improvement; dependence modelling.;

    Abstract : Preloading without a surcharge is a common method for ground improvement. Thereare however uncertainties related to the number of site investigations and the partialfactor method has been identified as a problem. READ MORE

  6. 10. Towards Deep Learning Accelerated Sparse Bayesian Frequency Estimation

    University essay from Lunds universitet/Matematisk statistik

    Author : Mika Persson; [2022]
    Keywords : Bayesian Statistics; Deep Learning; Frequency Estimation; Generative Adversarial Networks; Artificial Neural Networks; Statistical Modelling; Mathematics and Statistics;

    Abstract : The Discrete Fourier Transform is the simplest way to obtain the spectrum of a discrete complex signal. This thesis concerns the case when the signal is known to contain a small (unknown) number of frequencies, not limited to the discrete Fourier frequencies, embedded in complex Gaussian noise.
