Non-linear versus non-gaussian volatility modelsSchittenkopf, Christian, Dorffner, Georg, Dockner, Engelbert J. January 1999 (has links) (PDF)
One of the most challenging topics in financial time series analysis is the modeling of conditional variances of asset returns. Although conditional variances are not directly observable there are numerous approaches in the literature to overcome this problem and to predict volatilities on the basis of historical asset returns. The most prominent approach is the class of GARCH models where conditional variances are governed by a linear autoregressive process of past squared returns and variances. Recent research in this field, however, has focused on modeling asymmetries of conditional variances by means of non-linear models. While there is evidence that such an approach improves the fit to empirical asset returns, most non-linear specifications assume conditional normal distributions and ignore the importance of alternative models. Concentrating on the distributional assumptions is, however, essential since asset returns are characterized by excess kurtosis and hence fat tails that cannot be explained by models with suffcient heteroskedasticity. In this paper we take up the issue of returns' distributions and contrast it with the specification of non-linear GARCH models. We use daily returns for the Dow Jones Industrial Average over a large period of time and evaluate the predictive power of different linear and non-linear volatility specifications under alternative distributional assumptions. Our empirical analysis suggests that while non-linearities do play a role in explaining the dynamics of conditional variances, the predictive power of the models does also depend on the distributional assumptions.

The Discourse of Weight Control and the Selfdldavies@central.murdoch.edu.au, Deirdre Davies January 2003 (has links)
This thesis offers an exploration of the discourse of weight control and examines how its concepts and goals are incorporated into the way people perceive and
understand the self and others. The central focus is an analysis of the nexus between weight control and concerns surrounding excess weight. The analysis reveals the way discourses on the balanced body, the normalised body, the
healthy body, the natural body and the transformative body generate varying understandings of the normal, weight-controlled body and overweight body and in turn, how they give rise to different weight watching practices. It shows how the different ways of viewing the body also engender various visualisations of the subjects of weight control. It is argued the discourse of weight control is not
put into effect by subjugation but through the generation of a personal desire to be slender and weight-controlled. As such, the central inquiry of the thesis also
gives consideration to the impacts which discourses of weight control might have upon individuals in the constitution of self and identity. A sub-theme of the
analysis is a consideration of the possibilities people have to engage with the discourse of weight control, in particular those who are considered overweight.
Particular attention is paid throughout to the relationship between women and weight control. The findings are predominantly based upon content analysis of a
broad range of primary texts including medico-scientific texts, historical material, policy and public health documents, and popular written and audiovisual
media. The research is also informed to a less extent by participant observation at two weight loss centres and by semi-structured in-depth interviews with 13 women considered overweight by current standards.
