A procedure for the statistical characterization of the units of the Belgian soil map, published at a scale of 1:20 000, is described and illustrated. It makes use of the information of 8 962 soil profiles described and sampled during the Belgian
variation of some properties of a given soil map unit over different regions.
Estimates of long-term immigration to the United States : moving US statistics toward United Nations concepts
Country of origin ; Data ; Demography ; Estimation ; Immigration ; Methodology ; United States
US immigration data are revised to reflect the UN demographic concept of long-term immigration. The estimates of long-term immigration for 1983 are compared to official INS statistics on alien immigration. Significant differences emerge according
Etude théorique de la définition des unités spatiales de base en cartographie médicale. Il faut concilier le souci de finesse maximale et la nécessité d'analyser un nombre suffisant et non aléatoire de décès dans chaque unité. Applications

fauna in the north-south direction, which resulted from the overall zonal distribution of cool, temperate and hot areas. The correlation between the number of species and the area of a unit was not statistically significant in every case considered
This analysis considered the relationship between the occurrence of mammals and geographical location in Europe, as well as the size of biogeographical units. It was found that there was differentiation in the qualitative composition of the mammal
Topoedaphic unit analysis: a site classification system for reclaimed mined lands
Discriminant analysis ; Environment ; North Dakota ; Principal components analysis ; Soil ; Soil conservation ; Soil properties ; Statistics ; Topography ; United States ; Vegetation
The aim of this paper is to outline a land classification system for reclaimed mined lands based on the use of topoedaphic units. The AA. describe the statistical methods used to delineate topoedaphic units and the discriminant model developed
for topoedaphic unit classification. They use data from the Glenharold Mine, North Dakota, USA.
Countryside recreational access in the United States: a statistical comparison of rural districts

Statistical models are proposed that capture the essential features of the structure of a population composed of geographically defined groups and can encompass grouping processes and contextual effects. They are used to show how small effects

The west coast of Britain: statistical self-similarity VS. Characteristics scales in the landscape
Coastal environment ; Coastal geomorphology ; Concept ; England and Wales ; Fractal geometry ; Methodology ; Scale ; Shoreline ; Statistics ; United Kingdom
The west coast of Britain is examined to determine whether it is statistically self-similar or if there exist characteristic scales (i.e. complexity varies with scale). The relationship between complexity and scale for the coastline is more closely
studied using fractal analysis, and also with a non-fractal measure of complexity developed by the A. specifically to examine changes in complexity with scale. The applicability of the concept of statistical self-similarity and the fractal element model

units of hillslopes in southeastern Arizona. Simple statistical models, based upon hillslope gradient as well as a soil-slope factor were developed and validated for the estimation of percent rock-fragment covers on these units.
Correlation ; Distance ; Distribution of points ; Population ; Spatial aggregation ; Spatial analysis ; Spatial distribution ; Statistics ; United States of America
The paper presents an approach for spatial correlation analysis for count variables by comparing their cumulative spatial distributions. Using the concept of LSCDF in classical statistics, it shows that location-specific and its associated K-S-like
statistic, which indicate the magnitude of difference between the two spatial distributions, are highly consistent over different levels of spatial scale. The two LSCDFs can provide a geographic description of the two spatial distributions of population
