We take a fresh look at Theil’s BLUS residuals and ask why they have gone out of fashion. All our simulation experiments indicate that tests based on BLUS residuals have higher power than those based on the more popular recursive residuals, even in those cases (structural breaks) where intuition would favour the recursive residuals. JEL Classification: B23; C10; C13; C20

Changes in biodiversity owing to vegetation degradation resulting from widespread urbanization demands serious attention. However, the connection between vegetation degradation and urbanization appears to be complex and nonlinear, and deserves a series of long-term observations. On the basis of the Normalized Difference Vegetation Index (NDVI) and the image’s digital number (DN) in nighttime st...

Adiqa Kiani ABSTRACT Using Tornqvist-Theil Index, average annual total factor productivity (TFP) growth rate of all major and minor crops in NWFP is found to be 1.5 percent, during 1969-2004. The marginal internal rate of return to provincial investment in research for TFP growth was in the range of 34 to 42 percent over the same period. Almon distributed lag model has also been estimated, usin...

We propose a new compression algorithm that is tailored to database applications It can be applied to a collection of records and is especially e ective for records with many low to medium cardinality elds and numeric elds In addition this new technique sup ports very fast decompression Promising application domains include decision sup port systems DSS since fact tables which are by far the la...

The speciication and derivation of substitution for the de Bruijn representation of-terms is used to illustrate programming with a function-sequence monad. The resulting program is improved by interactive program transformation methods into an eecient implementation that uses primitive machine arithmetic. These transformations illustrate new techniques that assist the discovery of the arithmeti...

BACKGROUND The Great Recession of 2007-2009 was the most severe and lengthy economic crisis in the U.S. since the Great Depression. The impacts on the population were multi-dimensional, but operated largely through local labor markets. OBJECTIVE To examine differences in recession-related changes in county unemployment rates and assess how population and place characteristics shaped these pat...

Metrics are usually defined on a micro level like methods, classes and packages. These are failed to provide an adequate picture of the entire system effectively. By combine different metrics with varying output values and ranges to get insight in the evolution of the macro level system. We listed various metrics like Product, Project & Process and also various aggregation techniques in Traditi...

This article provides a look at business concentration for sales and assets for the period 1967 to 2002 based on Theil’s entropy, a measure adopted by several authors in earlier publications. For contrast, three other well-known measures of concentration, the HirschmanHerfindahl (HHI) index and the 4-firm and 8-firm concentration ratios, CR4 and CR8, were utilized. Data used were sales and asse...

background: dyslipidemia is considered an independent risk factor for coronary heart disease (chd). in the present study, we examined lipid profiles and paraoxonase 1 (pon1) activity and atherogenic indexes status and the relationship of pon1 activity by high-density lipoprotein (hdl) and atherogenic indexes in chd patients and healthy people. methods: the aim of the study was to compare pon1, ...
