The approach proposed to classify commercial banks into banks that have a high probability of revoking a license and reliable banks, as well as an information and logical model for identifying a group of banks (or one bank) among reliable banks that are attractive for investment. The probability of license revocation was assessed using a ...

The focus of this article is the methodological aspect of political activism determinants identifying; specifically variants of handling with categorical predictors which hypothetically explain the level of activism. When using regression for explaining the issue, one may transform such predictors into dummy variables. Such a popular solution makes the model bulky and causes troubles with ...

From 2007 to 2014 total fertility rate in Russia increased from 1.42 to 1.75. To what extent this growth is related to a package of family policy measures introduced in 2007? Although the maternity (family) capital program is the most well-known innovation of the 2007 reform, we argue that the new rules of monthly childcare ...

We analyze the dynamics of dialect loss in a cluster of villages in rural northern Russia based on a corpus of transcribed interviews, the Ustja River Basin Corpus. Eleven phonological and morphological variables are analyzed across 33 speakers born between 1922 and 1996 in a series of logistic regression models. We propose three characteristics for ...

In this study a CHAID-based approach to detecting classification accuracy heterogeneity across segments of observations is proposed. This helps to solve some important problems, facing a model-builder: (1) How to automatically detect segments in which the model significantly underperforms? and (2) How to incorporate the knowledge about classification accuracy heterogeneity across segments to partition observations ...

In most of current papers devoted to the analysis of protest-repression nexus, the research
design misses the dynamic nature of this nexus, which seems methodologically incorrect. The
analysis of the dynamics allows us to identify the role of various factors influencing the course of
this conflict. The variety of different dynamics of the number of protesters and the ...

Researchers have been improving credit scoring models for decades. The reason for this is following: an increase in the predictive ability of scoring even by small values can save a financial institution from a significant losses. As a result, many researchers have conclude that ensembles of classifiers or aggregated scorings have greater performance. However, ensembles ...
