Knowledge and innovation dynamics of the Northwest Russia under geopolitical changes
... indicator for region i; Yi is the absolute value of the indicator for region i; Ymax is the maximum absolute value of the indicator in the considered regions (in this study, for all indicators, this is St. Petersburg). Thus, during the correlation and regression analysis, we use not absolute values of the indicators but the relative ones, reflecting the gap between each region and the leader. This approach is consistent with the logic of the comparative cross-regional assessment used in the previous ...
The spread of the COVID-19 infection in Russia’s Baltic macro-region: internal differences

COVID-19 morbidity and mortality.
Amongst quantitative methods, regression analysis was employed most frequently to analyse the factors affecting the national and regional patterns of coronavirus spread. For example, Aleksandr Pilyasov, Natalya Zamyatina and Yegor Kotov proposed a regression model for all Russian ...

Application of Shapley value in a regression analysis
The application of the cooperative game theory model, Shapley value, for the estimation of the regression coefficients and the contribution of predictors to the general explainability of the model is considered. The necessary theoretical apparatus is systematized and the construction of Shapley estimates based on the coefficient of determination ...
Correlation-regression analysis of bitcoin characteristics
The article is devoted to the phenomenon of a money surrogate, introduced in the form of a bitcoin, a popular cryptocurrency. The purpose of the research is to study the influence of the price-per-unit value of the cryptocurrency on the indicator of the market capitalization of the bitcoin cryptocurrency through correlation-regression analysis. As a result of the research, the author becomes the first to prove the direct dependence of the mentioned indicators, namely, a strong relationship between...

Use of the genetic algorithm for devising a formula for liver volumetry
The authors propose a method of liver volumetry using anthropometric data and the data obtained during an ultrasound examination. The algorithm is built on the basis of a genetic algorithm with coefficients calculated using linear regression. It is shown that the new formula is more accurate than previously proposed ones. The algorithm can be used to work out volumetric formulas for other organs in radiological studies.

Innovation performance of Russia’s Northwestern regions: a comparative evaluation
... aided in devising a typology of regions and analysing changes in the position in a composite evaluation matrix. The findings demonstrate that Saint Petersburg and the Leningrad region comfortably outperform the other northwestern regions in innovation. Regression and correlation analysis reveals that innovation performance depends crucially on earlier achievements and currently available resources. The Novgorod region, however, is making headway without a marked change in the level of resources. Thus,...
Evaluating the efficiency of the research sector in Russian regions: a dynamic data envelopment analysis

We view DEA as an approach to evaluate the efficiency of objects’ performance, as we do regression analysis, the index method and stochastic production frontier analysis. The results of such evaluations, as a rule, underpin guidelines for increasing the efficiency of objects’ performance and help identify inefficient objects of systems ...
Analysis methodology for the relationship between the water flow and river levels by determining the dependence
... contains all the available data on average monthly discharges and water levels for the rivers under study, that provided the background for the hydrological series of these characteristics which are found to be in a close stochastic connection. Linear regression equations connect the average monthly discharges and water levels in the rivers under study. They also provide for the graphs of the relationship between the considered values, and the boundaries of their confidence intervals were calculated ...
Comparative analysis of students’ collective consciousness in the Russia-EU and Russia-China border regions: mathematical modelling

They examine the sociological phenomenon of ‘regional consciousness’ and substantiate the criteria for selecting the objects of research. It is the first time in sociology that logistic regression models reflecting the main characteristics of regional consciousness have been built. The article aims to confirm the multiplicity of types of regional consciousness and to demonstrate that in the socially homogeneous group, Russian graduate ...

The Relationship between Heart Rhythm Variability and the Heart Rate in Adolescents and Young Adults
In this article, we study the degree of dependence of heart rate variability in healthy adolescents and young adults on the average rhythm frequency. In the study group, heart rate variability decreased as heart rate grew. Although there was no difference in the increase in the heart rate, the variability of the heart rate decreased less significantly in young women than in young men. An increase in the average heart rate by 10 cardiac cycles per minute reduced the heart rate variability by 25.6...
Personal determinants of somatic reactions in adolescents
... traits of adolescents and the development of somatic reactions. The author confirms numerous survey data concerning the association of dysfunctional personal characteristics and the severity of somatic symptoms in the adolescent population. Multiple regression analysis demonstrates that a high degree of somatic reactions are typical of adolescents with emotional instability and a hostile view of the world. The author proves a "buffer" role of social support; partial leveling of dysfunctional ...
