Development of a module of a software and information system for the study of dependencies between indicators of heart rate variability of athletes by factor analysis

The article describes the module of the software and information system developed by the authors and designed to study the dependencies between the indicators of heart rate variability of athletes by factor analysis. To carry out factor analysis, the principal component method is used, as well as the orthogonal rotation method in conjunction with the Bartlett sphericity test and the Kaiser method. The results of the analysis are matrices of eigenvalues of factors, matrices of factor loads and ring diagrams of significant factors.
