  1. 6. Copula modeling for Portfolio Return Analysis

    University essay from KTH/Matematik (Avd.)

    Author : Markus Gustafsson; [2023]
    Keywords : applied mathematics; copulas; tillämpad matematik; copulas;

    Abstract : In this thesis, we investigate the advantages of using high-dimensional copula modeling to understand the riskiness of portfolio investments and to more realistically estimate future portfolio values. Our approach involves benchmarking some pre-determined fitted copulas to the 0. READ MORE

  3. 7. Copula approach to fitting bivariate time series

    University essay from Lunds universitet/Matematisk statistik

    Author : Jun Wang; [2023]
    Keywords : VaR; Copula; ARMA-GARCH; Extreme Value Theory; GPD; Hill estimator; Mathematics and Statistics;

    Abstract : We apply the GARCH-copula method to estimate Value at Risk (VaR) for European and Stockholm stock indices. First, marginal distributions are estimated by the ARMA-GARCH model with normal, Student-t, and skewed t distributions. READ MORE

  4. 8. Copula Modelling of High-Dimensional Longitudinal Binary Response Data

    University essay from KTH/Matematik (Avd.)

    Author : Nils Henningsson; [2022]
    Keywords : Copula; latent model; variational inference; Copula; latent modell; variational inference;

    Abstract : This thesis treats the modelling of a high-dimensional data set of longitudinal binary responses. The data consists of default indicators from different nations around the world as well as some explanatory variables such as exposure to underlying assets. READ MORE

  5. 9. Improving term structure measurements by incorporating steps in a multiple yield curve framework

    University essay from Linköpings universitet/Produktionsekonomi

    Author : Gustav Villwock; Clara Rydholm; [2022]
    Keywords : Finance; Interest rates; Term structure measurement; Monte Carlo; Financial mathematics; Yield curve; Policy rates; Multiple yield curve framework; Stochastic programming; Risk factor modeling; Hedging; Performance attribution; Principle component analysis; GARCH; Maximum likelihood estimation; Copula;

    Abstract : By issuing interest rate derivative contracts, market makers such as large banks are exposed to undesired risk. There are several methods for banks to hedge themselves against this type of risk; one such method is the stochastic programming model developed by Blomvall and Hagenbjörk (2022). READ MORE

  6. 10. Estimation of severe crash frequency using two surrogates

    University essay from Lunds universitet/Matematisk statistik

    Author : Zhankun Chen; [2022]
    Keywords : Multivariate Extreme Value distributions; Copula; Extreme Value Theory; Crash frequency; Surrogate Meausre of Safety; Road safety; Mathematics and Statistics;

    Abstract : This thesis is concerned with the estimation of crash frequency based on the bivariate modeling of surrogate measures of safety (SMoS), which serve as indicators for traffic risk. Using the SMoS, any traffic conflict between two road users can be described by their proximity together with their hypothetical consequence. READ MORE
