    Simulation of the crisis contagion process between countries with different levels of socio-economic development
    (CEUR Workshop Proceedings, 2019) Strelchenko I.I.; Matviychuk A.; Vashchaiev S.; Velykoivanenko H.
    The paper contains a detailed analysis of the occurrence and contagion of crisis phenomena in countries with different levels of economic development. As part of the study, a correlation analysis of classification characteristics was carried out for the preliminary division of countries into classes. The usage of neural networks tools for the mathematical modelling of the processes of transboundary contagion of crisis is substantiated. A general scheme of the system of models of transboundary distribution of crisis phenomena between countries has been built. At the first level of the scheme for dividing countries into separate groups according to types of reaction to crisis phenomena, it was proposed to cluster them using self-organizing maps. At the second level of the scheme it was decided to use a perceptron-type neural network to predict the effects of crisis transfers.

    The Use of Non-Parametric Criteria for the Evaluation of Similar Patterns in the Behaviour of the Economic System
    (Polgári szemle, 2017) Strelchenko I.I.
    The statistics made by the International Monetary Fund of a sample of 30 countries analysed to assess the degree of synchronicity of changes under the impact of the crisis on macroeconomic indicators such as increase in: GDP, the exchange rate of the national currency; a country’s international investment position (which characterizes the external liabilities of residents to non-residents); foreign exchange reserves; the value of government bonds. In order to quantify the changes observed, the values of the Kendall concordance coefficient were calculated for equal periods of time – in the crisis and post-crisis periods.
