16. Applications of Bayesian Econometrics to Financial Economics
Sammanfattning : This PhD thesis consists of four separate papers. What these papers have in common is that Bayesian Econometrics, in combination with Markov chain Monte Carlo (MCMC) methods, is applied to study various problems in financial economics. LÄS MER
17. Timing and Schedulability Analysis of Real-Time Systems using Hidden Markov Models
Sammanfattning : In real-time systems functional requirements are coupled to timing requirements, a specified event needs to occur at the appropriate time. In order to ensure that timing requirements are fulfilled, there are two main approaches, static and measurement-based. LÄS MER
18. Numerical simulation of well stirred biochemical reaction networks governed by the master equation
Sammanfattning : Numerical simulation of stochastic biochemical reaction networks has received much attention in the growing field of computational systems biology. Systems are frequently modeled as a continuous-time discrete space Markov chain, and the governing equation for the probability density of the system is the (chemical) master equation. LÄS MER
19. Simulation-based Inference : From Approximate Bayesian Computation and Particle Methods to Neural Density Estimation
Sammanfattning : This doctoral thesis in computational statistics utilizes both Monte Carlo methods(approximate Bayesian computation and sequential Monte Carlo) and machine-learning methods (deep learning and normalizing flows) to develop novel algorithms for inference in implicit Bayesian models. Implicit models are those for which calculating the likelihood function is very challenging (and often impossible), but model simulation is feasible. LÄS MER
20. Some Extensions of Fractional Ornstein-Uhlenbeck Model : Arbitrage and Other Applications
Sammanfattning : This doctoral thesis endeavors to extend probability and statistical models using stochastic differential equations. The described models capture essential features from data that are not explained by classical diffusion models driven by Brownian motion.New results obtained by the author are presented in five articles.
