Despite their success and widespread usage in industry and business, ES methods have received little attention from the statistical community. We investigate three types of statistical models that have been found to underpin ES methods. They are ARIMA models, state space models with multiple...

While much attention has focused on the modelling of the interdependencies between key aggregates and stock indices in industrialised countries, this thesis is focused on investments in emerging markets and real estate – two research branches that have up to now not been investigated to a...

In this paper I derive the asymptotics of the exact, Euler, and Milstein MLestimators for diffusion models, including general nonstationary diffusions. Thoughthere have been many estimators for the diffusion model, their asymptotic propertieswere generally unknown. This is especially true for...

An important empirical fact in financial market is that return distributions are often skewed and heavy-tailed. This paper employs maximum likelihood estimation to estimate the five parameters of generalized hyperbolic distribution, a highly flexible heavy-tailed distribution. The estimation...
