Wavelet Coherence as a Tool for Studying of Economic Dynamics in Infocommunication Systems

Analysis of economic dynamics is an important task. Such an analysis makes it possible to identify potential threats for economic development, to analyze economic risks. This is important for economic security and economic security management. In order to conduct a study of economic dynamics, infocommunication systems can be used. For this study, it is necessary to choose mathematical methods and models. We consider wavelet ideology for analyzing economic security. We suggest using wavelet coherence to build portraits of economic dynamics. The results are given on the example of real data for the banking sector of the economy of Ukraine.
