The behaviour of a near-critical sample of SF6, bounded by container walls with finite thermal properties, was studied in space during the 1994 IML-2 mission. Experiments were performed in the range 2500 to 1 mK above the critical point in which simultaneous density and temperature measurements...

Design of Experiments and Reliability are two well known statistical techniques very useful in efforts towards the improvement of industrial products. Usually these two tools are applied separately, leading practitioners to believe they are fit to solve problems of a different matter. This...

The log normal reserving model is considered. The contribution of the paper is to derive explicit expressions for the maximum likelihood estimators. These are expressed in terms of development factors which are geometric averages. The distribution of the estimators is derived. It is shown that...

While making a statistical model it is important both, to find a theoretical distribution function that would characterize empirical frequency distribution and to choose a suitable method of parameter estimate of such model. Recently used type of a theoretical model of income distribution (the...

This paper investigates the generalized parametric measurement methods of aggregate operational risk in compliance with the regulatory capital standards for operational risk in the New Basel Capital Accord ("Basel II"). Operational risk is commonly defined as the risk of loss resulting from...

This paper presents two approaches to modeling the use of IMF resources in order to gauge whether the recent decline in credit outstanding is a temporary or a permanent phenomenon. The two approaches-the time series behavior of credit outstanding and a two-stage program selection and access...

This paper provides a selective overview of nonlinear exchange rate models recently proposed in the literature and assesses their contribution to understanding exchange rate behavior. Two key questions are examined. The first question is whether nonlinear autoregressive models of real exchange...

Following record low interest rates and fast depreciating U.S. dollar, crude oil prices became under rising pressure and seemed boundless. Oil price process parameters changed drastically in 2003M5-2007M10 toward consistently rising prices. Short-term forecasting would imply persistence of...
