Index numbers of prices and quantities are estimated in the framework of a two-way analysis of variance, based on the ideas of H. Theil and K. Banerjee. Topics include aggregation, multidimensional indices, and non-spherical errors. The method is applied to the commodity exports of developing nations. Copyright (c) 1997 Eric Blankmeyer

A new indexing method is presented which is capable of indexing multiple crystal lattices from narrow wedges of diffraction data. The method takes advantage of a simplification of Fourier transform-based methods that is applicable when the unit-cell dimensions are known a priori. The efficacy of this method is demonstrated with both semi-synthetic multi-lattice data and real multi-lattice data ...

This paper outlines the evolution of the theory of economic policy from the classical contributions of Frisch, Hansen, Tinbergen and Theil to situations of strategic interaction. Andrew Hughes Hallett has taken an active and relevant part in this evolution, having contributed to both the development and recent rediscovery of the classical theory, with possible relevant applications for model bu...

We study the self-duality operator on conic 4-manifolds. The self-duality operator can be identified as a regular singular operator in the sense of Brüning and Seeley, based on which we construct its parametrizations and closed extensions. We also compute the indexes.

While software metrics are commonly used to assess software maintainability and study software evolution, they are usually defined on a micro-level (method, class, package). Metrics should therefore be aggregated in order to provide insights in the evolution at the macro-level (system). In addition to traditional aggregation techniques such as the mean, recently econometric aggregation techniqu...

global warming has brought about changes in meteorological variable time series. these changes, accompanied with serious human intervention in nature, has resulted in hydrological changes. so the effects can be tracked down by the trend of the time series. the purpose of this study is to analyze and compare the monthly and annual trends of temperature, precipitation as well as stream flow time ...

The paper examines the linkages between gender of household heads, education and household poverty in Nigeria between 1980 and 1996. Data analyzed were obtained from four national consumer expenditure surveys conducted in Nigeria in 1980, 1985, 1992 and 1996 by the Federal Office of Statistics. Adjustments were made for price differentials over time and across regions of the country. However, o...
