Повторяющиеся наблюдения, называемые связями, приводят к неоднозначному ранжированию. Обычно элементам связанной группы присваивается среднеарифметический ранг. В результате изменяются статистические решающие правила, поскольку статистика критерия меняет свое распределение. Настоящая статья посвящена исследованию мощности различных критериев при наличии связей.</p></abstract><trans-abstract xml:lang="en"><p>The paper considers research of various nonparametric methods of checking a hypothesis of randomness of sampled data in a situation when these data contain repeating (tied) observations. The repeating observations named ties lead to ambiguous ranking. The arithmetic-mean rank is usually assigned to elements of the tied group. As a result, statistical decision rules change as the criterion statistics changes its distribution. This paper is devoted to research of capacity of various criteria at presence of ties.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>связь</kwd><kwd>связанная группа</kwd><kwd>ранг</kwd><kwd>инверсия</kwd><kwd>критерий Спирмена</kwd><kwd>критерий Кендалла</kwd><kwd>интегральный критерий</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tied group</kwd><kwd>rank</kwd><kwd>inversion</kwd><kwd>Spearman test</kwd><kwd>Kendall test</kwd><kwd>integral test</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">Холлендер М., Вулф Д.
