Представлены три интеграла, позволяющие рассчитывать моменты векторного гауссовского распределения, а также формулы полной вероятности и союз Байеса. Приводятся доказательства полученных результатов. Вывод интегралов выполнен на основе метода исключения Гаусса. Формулы полной вероятности и Байеса получены на основе доказанных интегралов. Представленные интегралы и интегральные преобразования могут быть использованы в различных вероятностных приложениях, например в теории статистических решений, в частности, в теории дуального управления, а также как табличные интегралы в различных областях исследований. На основе полученных результатов рассчитаны байесовские оценки коэффициентов множественной функции регрессии.</p></abstract><trans-abstract xml:lang="en"><p>This paper is dedicated to the integrals and integral transformations related to the probability density function of the vector Gaussian distribution and arising in probability applications. Herein, we present three integrals that permit to calculate the moments of the multivariate Gaussian distribution. Moreover, the total probability formula and Bayes formula for the vector Gaussian distribution are given. The obtained results are proven. The deduction of the integrals is performed on the basis of the Gauss elimination method. The total probability formula and Bayes formula are obtained on the basis of the proven integrals. These integrals and integral transformations could be used, for example, in the statistical decision theory, particularly, in the dual control theory, and as table integrals in various areas of research. On the basis of the obtained results, Bayesian estimations of the coefficients of the multiple regression function are calculated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>векторное гауссовское распределение</kwd><kwd>многомерные интегралы</kwd><kwd>формула полной вероятности</kwd><kwd>формула Байеса</kwd><kwd>множественная функция регрессии</kwd><kwd>байесовские оценки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vector Gaussian distribution</kwd><kwd>multidimensional integrals</kwd><kwd>total probability formula</kwd><kwd>Bayes formula</kwd><kwd>multiple regression function</kwd><kwd>Bayesian estimations</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">Fel’dbaum A.
