The aim of this article is to use probabilistic ideas to study predictive reasoning based on hypotheses and models, but without using Ito calculus, without writing any stochastic differential equations, in fact without writing any formulas at all. The aim is to extract from the study of...

Secondly, we identify outliers using intervention analysis and conditional heteroscedasticity model. These … announcements on crude inventories. We show that outliers can bias the estimation of the persistence of the volatility. Taking into …

Regulation and Risk management in banks depend on underlying risk measures. In general this is the only purpose that is … seen for risk measures. In this paper, we suggest that the reporting of risk measures can be used to determine the loss … distribution function for a financial entity. We demonstrate that a lack of sufficient information can lead to ambiguous risk …

Starting from the requirement that risk measures of financial portfolios should be based on their losses, not their … gains, we define the notion of loss-based risk measure and study the properties of this class of risk measures. We … characterize loss-based risk measures by a representation theorem and give examples of such risk measures. We then discuss the …
