Предложены методы анализа характеристик эффективности (вероятностей ошибок первого и второго рода, а также среднего числа наблюдений) последовательных статистических тестов, основанные на приближении тестовой статистики и использующие теорию поглощающих цепей Маркова. Предложенные методы позволяют вычислять характеристики эффективности последовательных статистических тестов не только для гипотетической модели данных, но и при отклонениях от этой модели, что может быть использовано при анализе робастности последовательных тестов. </p></abstract><trans-abstract xml:lang="en"><p>Sequential statistical tests for simple hypotheses on parameters of probability distributions of independent observations, as well as of Markov chains are considered in the article. Methods for analysis of performance characteristics (I and II type error probabilities, conditional expected sample sizes) of sequential statistical tests are constructed both on the basis of the approximations of test statistics and on the basis of absorbing Markov chain theory. The proposed methods allow assessing the performance characteristics of sequential statistical tests not only for the hypothetical model of data, but also under deviations from this model, which can be used for robustness analysis of sequential tests. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>последовательный тест</kwd><kwd>вероятность ошибки</kwd><kwd>среднее число наблюдений</kwd><kwd>цепь Маркова</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sequential test</kwd><kwd>error probability</kwd><kwd>expected number of observations</kwd><kwd>Markov chain</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке ГПНИ «Конвергенция-2020».</funding-statement><funding-statement xml:lang="en">The research is supported by the State Research Program «Convergence-2020».</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Wald, A.
