Recently, $ p $-value combination tests based on regularly-varying-tailed distributions, such as the Cauchy combination test and harmonic mean $ p $-value, have attracted attention for their robustness to unknown dependence. This paper provides a theoretical and empirical evaluation of these methods under an asymptotic regime where the number of $ p $-values is fixed and the global test significance level approaches zero. We examine two types of dependence among the $ p $-values. First, when $ p $-values are pairwise asymptotically independent, such as with bivariate normal test statistics with no perfect correlation, we prove that these combination tests are asymptotically valid. However, they become equivalent to the Bonferroni test as the significance level tends to zero for both one-sided and two-sided $ p $-values. Empirical investigations suggest that this equivalence can emerge at moderately small significance levels. Second, under pairwise quasi-asymptotic dependence, such as with bivariate $ t $-distributed test statistics, our simulations suggest that these combination tests can remain valid and exhibit notable power gains over the Bonferroni test, even as the significance level diminishes. These findings highlight the potential advantages of these combination tests in scenarios where $ p $-values exhibit substantial dependence. Our simulations also examine how test performance depends on the support and tail heaviness of the underlying distributions.<\/jats:p>","DOI":"10.1093\/biomet\/asaf038","type":"journal-article","created":{"date-parts":[[2025,5,28]],"date-time":"2025-05-28T07:45:34Z","timestamp":1748418334000},"source":"Crossref","is-referenced-by-count":7,"title":["Aggregating dependent signals with heavy-tailed combination tests"],"prefix":"10.1093","volume":"112","author":[{"given":"Lin","family":"Gui","sequence":"first","affiliation":[{"name":"Department of Statistics, The University of Chicago , 5747 South Ellis Avenue , Chicago, Illinois 60637,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuchao","family":"Jiang","sequence":"additional","affiliation":[{"name":"Departments of Statistics and Biology, Texas A&M University , 155 Ireland Street, College Station, Texas 77843,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingshu","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Statistics, The University of Chicago , 5747 South Ellis Avenue , Chicago, Illinois 60637,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2025,5,30]]},"reference":[{"key":"2026032607103752300_asaf038-B1","doi-asserted-by":"crossref","first-page":"107","DOI":"10.1007\/s10687-006-0011-1","article-title":"Tail asymptotics for the sum of two heavy-tailed dependent risks","volume":"9","author":"Albrecher","year":"2006","journal-title":"Extremes"},{"key":"2026032607103752300_asaf038-B2","doi-asserted-by":"crossref","first-page":"5","DOI":"10.1007\/s10479-009-0658-5","article-title":"Efficient simulation of tail probabilities of sums of correlated lognormals","volume":"189","author":"Asmussen","year":"2011","journal-title":"Ann.
