1. Some Investigations into the Class of Exponential Power Distributions
Abstract : In this thesis, methods are developed relating to the exponential power class of distributions.Paper I considers Bayesian linear mixed models where the usual normality assumption is replaced by the multivariate exponential power distribution. Particular focus lies on Bayesian testing of the fixed effects. READ MORE

2. Properties and tests for some classes of life distributions
Abstract : A life distribution and its survival function F = 1 - F with finitemean y = /q F(x)dx are said to be HNBUE (HNWUE) if F(x)dx < (>)U exp(-t/y) for t > 0. The major part of this thesis deals with the classof HNBUE (HNWUE) life distributions. READ MORE

3. Testing and estimation in labour supply and duration models
Abstract : Estimation and testing in labour supply and unemployment duration models are studied. In the first two papers estimation techniques designed to account for quantity constraints and perceived tax scales are developed, while the remaining three papers focus on specification tests.

5. Modeling the covariance matrix of financial asset returns
Abstract : The covariance matrix of asset returns, which describes the fluctuation of asset prices, plays a crucial role in understanding and predicting financial markets and economic systems. In recent years, the concept of realized covariance measures has become a popular way to accurately estimate return covariance matrices using high-frequency data. READ MORE
