Russian Science Citation Index

The article presents the results of the rating of Russian economic journals, the methodology of which is based on a combination of bibliometric data and expert interviews. Processing of the statistical information system of Russian science citation index (RINC) allows us to form a “primary” list of the best journals in the country. Expert evaluation of the list makes it possible to reorganize it with regard to the scientific level of periodicals and get the “secondary” list. The merger of two ranking systems forms the basis of obtaining the final ranking of economic journals. It is shown that the leading part of the constructed rating forms a kind of the Diamond List of journals, which on the whole agrees with similar lists obtained in earlier studies by other authors.

Model Structures

Empirical research in marketing often is, at least in parts, exploratory. The goal of exploratory research, by definition, extends beyond the empirical calibration of parameters in well established models and includes the empirical assessment of different model specifications. In this context researchers often rely on the statistical information about parameters in a given model to learn about likely model structures. An example is the search for the 'true' set of covariates in a regression model based on confidence intervals of regression coefficients. The purpose of this paper is to illustrate and compare different measures of statistical information about model parameters in the context of a generalized linear model: classical confidence intervals, bootstrapped confidence intervals, and Bayesian posterior credible intervals from a model that adapts its dimensionality as a function of the information in the data. I find that inference from the adaptive Bayesian model dominates that based on classical and bootstrapped intervals in a given model.

This article introduces statistical data on the development of the copper industry in the Sverdlovsk region in 1940-1953. On the example of the industry, we consider such a phenomenon as indirect damage from the fighting of 1941-1945 for the industrial Urals. The related changes in the territorial organization of the productive forces of the copper industry in the region are shown.

Epidemiological Situation

The most common method of statistical analysis in epidemiology is the retrospective analysis of infectious disease cases. Recorded in the system of Federal statistical observation they are not bound on specific localities, but to the areas of territorial bodies’ of Russian Federation Health Care Ministry and Rospotrebnadzor responsibility. In order to load the information into databases and use them in GIS, the spatial reference of statistical information to specific coordinates of suspected infection sites or to a specific administrative or specially designated territory having a spatial description is necessary. The aim of the work is to analyze the system of classification and coding administrative and specially allocated territories of the Russian Federation at various levels for the implementation of multifactor analysis of the epidemiological situation with the involvement of climatic, landscape, land management and other data, as well as to solve other problems of the territories spatial development.

Reduction Index

Modern portfolio theory deals with the problem of selecting a portfolio of financial assets such that the expected return is maximized for a given level of risk. The forecast of the expected individual assets’ returns and risk is usually based on their historical returns. In this work, we consider a situation in which the investor has non-historical additional information that is used for the forecast of the expected returns. This implies that there is no obvious statistical risk measure any more, and it poses the problem of selecting an adequate set of diversification constraints to mitigate the risk of the selected portfolio without losing the value of the non-statistical information owned by the investor. To address this problem, we introduce an indicator, the historical reduction index, measuring the expected reduction of the expected return due to a given set of diversification constraints. We show that it can be used to grade the impact of each possible set of diversification constraints. Hence, the investor can choose from this gradation, the set better fitting his subjective risk-aversion level.
