6. Approximating Stochastic Partial Differential Equations with Finite Elements: Computation and Analysis
Sammanfattning : Stochastic partial differential equations (SPDE) must be approximated in space and time to allow for the simulation of their solutions. In this thesis fully discrete approximations of such equations are considered, with an emphasis on finite element methods combined with rational semigroup approximations. LÄS MER
7. Topics in Simulation and Stochastic Analysis
Sammanfattning : Paper A investigates how to simulate a differentiated mean in cases where interchanging differentiation and expectation is not allowed. Three approaches are available, finite differences (FD's), infinitesimal perturbation analysis (IPA) and the likelihood ratio score function (LRSF) method. LÄS MER
8. Multivariate Aspects of Phylogenetic Comparative Methods
Sammanfattning : his thesis concerns multivariate phylogenetic comparative methods. We investigate two aspects of them. The first is the bias caused by measurement error in regression studies of comparative data. We calculate the formula for the bias and show how to correct for it. LÄS MER
9. Empirical Studies in Consumption, House Prices and the Accuracy of European Growth and Inflation Forecasts
Sammanfattning : This thesis consists of four essays: Essay 1: The Role of Wealth in the Aggregated Consumption Function using an Error Correction Approach: Swedish Evidence from the years 1970 - 1993, an aggregated consumption function based on the life cycle hypothesis using the error correction methodology is estimated for Sweden. Aggregate wealth is spilt into net financial and housing wealth. LÄS MER
10. Learning Stochastic Nonlinear Dynamical Systems Using Non-stationary Linear Predictors
Sammanfattning : The estimation problem of stochastic nonlinear parametric models is recognized to be very challenging due to the intractability of the likelihood function. Recently, several methods have been developed to approximate the maximum likelihood estimator and the optimal mean-square error predictor using Monte Carlo methods. LÄS MER
