Показано, что вклад временного фактора в вариации времен пробега волн P по наблюдениям за 248 взрывами на станции BRVK статистически значим, величина тренда равна 4.31 ±.0.8  мс/год, хотя его доля в вариациях времени пробега составляет менее 0.1%. При раздельной оценке по взрывам на Юкка-Флет и Пахьют-Меса величина тренда составила 3.18 ± 1.15 и 4.24 ± 1.23 мс/год соответственно.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>The reliability of determining the time trend of the travel time of longitudinal waves P excited by nuclear explosions at the Nevada Test site and recorded at the BRVK seismic station was assessed based on multiple regression analysis supplemented by the initial sampling method. It is shown that the contribution of the time factor to the variations in the travel times of the P waves according to observations of 248 explosions at the BRVK station is statistically significant, the trend value is 4.31 ± 0.8 ms/year, although its share in the travel time variations is less than 0.1%. When the explosions at Yucca Flat and Pahute Mesa were evaluated separately, the trend values were 3.18 ± 1.15 and 4.24 ± 1.23 ms/year, respectively.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>временной тренд времени пробега</kwd><kwd>регрессионный анализ</kwd><kwd>метод начальной выборки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>time trend of travel time</kwd><kwd>regression analysis</kwd><kwd>bootstrapping</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена при финансовой поддержке по проекту №125012200561-3</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title></ref-list><fn-group><fn fn-type="conflict"><p>The authors declare that there are no conflicts of interest present.</p></fn></fn-group></back></article>
