L'A., économiste japonais essaie d'évaluer à partir des statistiques de base la réalité du commerce extérieur russe. Examen des données de la période 1985-mi 1994: incohérences et défauts du système de comptabilité (classifications douteuses
A statistical method for analyzing the spatial relationship between the distribution of activity points and the distribution of activity continuously distributed over a region

. The A. investigates American mobility, through description and classification of migration carrers. Statistical methods for the procedures are proposed. The field survey is conducted in Santa Barbara (California) and Lexington (Kentucky). - (KA)

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.

The data generation process underlying regional house prices in the UK is investigated using new statistical tests (12 regions, 1968-93 period). It is found that causal flows tend to be northwards. These results are largely independent

Major, trace, and rare earth element analyses of volcanic glass are used separately or in combination for correlating Quaternary tephras, often by graphical or simple comparative methods. The AA. have taken a statistical approach using discriminant
