1. Exchange Rate Analysis Between the U.S. Dollar and the Japanese Yen
University essay from Uppsala universitet/Statistik, AI och data scienceAbstract : The exchange data between the U.S. Dollar and Japanese Yen are analyzed with three models called the Auto-Regressive Integrated Moving- Average (ARIMA) model, the Generalized Auto-Regressive Conditional Heteroscedastic (GARCH) model, and the Fractional Differencing model.

2. Applying Peaks-Over-Threshold for Increasing the Speed of Convergence of a Monte Carlo Simulation
University essay from KTH/Matematik (Avd.)Abstract : This thesis investigates applying the semiparametric method Peaks-Over-Threshold on data generated from a Monte Carlo simulation when estimating the financial risk measures Value-at-Risk and Expected Shortfall. The goal is to achieve a faster convergence than a Monte Carlo simulation when assessing extreme events that symbolise the worst outcomes of a financial portfolio. READ MORE

5. Optimizing multigrid smoothers using GLT theory
University essay from Lunds universitet/Matematik LTH; Lunds universitet/MatematikcentrumAbstract : Multigrid algorithms are algorithms used to find numerical solutions to differential equations using a hierarchy of grids of different coarseness. This exploits the fact that short-wavelength components of the solutions converges at a faster rate than the long-wavelength components when using some basic iterative methods, such as the Jacobi method or the Gauss-Seidel method.
