Эти случайные векторы могут иметь произвольные многомерные непрерывные законы распределения. Ранее в рамках энтропийного подхода были получены показатели оценки тесноты корреляционной взаимосвязи между компонентами одного случайного вектора и между двумя случайными векторами. Цель работы — обобщение полученных ранее результатов на случай нескольких случайных векторов. Предложено аналитическое выражение для коэффициента тесноты взаимозависимости между случайными векторами. Он выражается через коэффициенты детерминации условных регрессий между компонентами случайных векторов. Для введенной скалярной меры взаимосвязи получен ряд частных результатов, которые оказались известными коэффициентами корреляционной связи. Для случая гауссовских случайных векторов выведена более простая формула. Она выражается через определители каждого из случайных векторов и определитель их объединения. Предложенный коэффициент может использоваться для исследования сетевых структур, состоящих из множества подсистем. В частности, введен коэффициент корреляции системы в вершине. Данная мера позволяет однозначно оценивать тесноту взаимозависимости между несколькими случайными векторами произвольных размерностей. Ее можно практически использовать на реальных выборках данных. Приведен пример расчета тесноты взаимосвязи между тремя гауссовыми случайными векторами.</p></abstract><trans-abstract xml:lang="en"><p>The problem of estimating the closeness of co-relation (interdependence) between several random vectors of arbitrary dimension is considered. These random vectors can have arbitrary multidimensional continuous distribution laws. Earlier, within the framework of the entropy approach, indicators were obtained for estimating the closeness of the correlation relationship between the components of one random vector and between two random vectors. The goal of the study is to generalize the previously obtained results to the case of several random vectors. The analytical expression for the coefficient of the closeness of co-relation between several random vectors is obtained. This coefficient is expressed through the indices of determination of conditional regressions between the components of random vectors. For the introduced scalar measure of the relationship, a number of particular results were obtained, which turned out to be known correlation coefficients. A rather simple formula expressed through the determinants of each random vector and the determinant of their combination is derived for the case of Gaussian random vectors. The proposed coefficient can be used to study the network structures consisting of many subsystems. In particular, the interpretation of the correlation coefficient between the elements of the network structure and the other elements can be introduced as the correlation coefficient of the system at the vertex. The introduced measure is quite simply interpretable and allows an unambiguous assessing of the closeness of co-relation between several random vectors of arbitrary dimensions and can be used on real data samples. An example of calculating the closeness of the co-relation between three Gaussian random vectors is presented.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>случайный вектор</kwd><kwd>взаимозависимость</kwd><kwd>мера</kwd><kwd>дифференциальная энтропия</kwd><kwd>индекс детерминации</kwd><kwd>корреляционная матрица</kwd></kwd-group><kwd-group xml:lang="en"><kwd>random vector</kwd><kwd>co-relation (interdependence)</kwd><kwd>measure</kwd><kwd>differential entropy</kwd><kwd>index of determination</kwd><kwd>correlation matrix</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Hair J.
