We use consumer price data for 205 cities/regions in 21 countries to study PPP deviations before, during and after the major currency crises of the 1990s. We combine data from industrialized nations in North America (Unites States, Canada and Mexico), Europe (Germany, Italy, Spain and Portugal),...

The problem of testing homogeneity in contingency tables when the data are spatially correlated is considered. We derive statistics defined as divergences between unrestricted and restricted estimated joint cell probabilities and we show that they are asymptotically distributed as linear...

The use of “radar charts” is an increasingly popular way to present spatial data in a visually interesting format. Some authors recommend using “filled radar charts” to compare the performance of observational units. Filled radar charts are not appropriate for such comparisons because...

This contribution discusses the problemof providing measures of significance ofprediction results when the predictionswere generated from spatial databases forlandslide hazard mapping. The spatialdatabases usually contain map informationon lithologic units, land-cover units,topographic elevation...

Building the new countryside construction database plays an important role in improving the construction efficiency, and enhancing the level of major project management. On the basis of detailed analysis of features of the new countryside construction data, we give an overview of the database...

An asymptotic theory is developed for nonparametric and semiparametric series estimation under general cross-sectional dependence and heterogeneity. A uniform rate of consistency, asymptotic normality, and sufficient conditions for convergence, are established, and a data-driven studentization...

The generation and use of spatial information has significantly increased in recent years. Its importance has been magnified by the INSPIRE Directive, which has subsequently led to specific requirements within several legislative frameworks, such as the Water Framework and Noise Directives, for...

This paper reports the findings of a survey in 2009 of European practitioners who face problems related to accessing and using spatial data when preparing reports for Environmental Impact Assessments (EIAs) and Strategic Environmental Assessments (SEAs). The survey was designed to be comparable...

The article discusses an essential problem of spatial econometrics which is the construction of a spatial weight matrix. This matrix expresses potential spatial interactions between the researched areas and forms the basis for spatial analyses. The objective of the paper was to consider various...
