It has properties similar to the Pearson correlation, but differs in two significant ways: (i) it is designed to measure dependence between curves; and (ii) it focuses only on extreme curves. The new coefficient is derived within the framework of regular variation in Banach spaces. A consistent estimator is proposed and justified by an asymptotic analysis and a simulation study. The usefulness of the new coefficient is illustrated using financial and climate functional data.<\/jats:p>","DOI":"10.1093\/biomet\/asaf077","type":"journal-article","created":{"date-parts":[[2025,10,28]],"date-time":"2025-10-28T12:54:57Z","timestamp":1761656097000},"source":"Crossref","is-referenced-by-count":0,"title":["Extremal correlation coefficient for functional data"],"prefix":"10.1093","volume":"113","author":[{"given":"M","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Statistics, West Virginia University , PO Box 6310 , Morgantown, 26505 West Virginia, U.S.A"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P","family":"Kokoszka","sequence":"additional","affiliation":[{"name":"Department of Statistics, Colorado State University , Fort Collins, 80523 Colorado, U.S.A"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2025,10,31]]},"reference":[{"key":"2026032607085511300_asaf077-B1","doi-asserted-by":"crossref","first-page":"661","DOI":"10.1137\/070710111","article-title":"Power\u2013law distributions in empirical data","volume":"51","author":"Clauset","year":"2009","journal-title":"SIAM Rev."},{"key":"2026032607085511300_asaf077-B2","doi-asserted-by":"crossref","first-page":"104375","DOI":"10.1016\/j.spa.2024.104375","article-title":"Regular variation in Hilbert spaces and principal component analysis for functional extremes","volume":"174","author":"Cl\u00e9men\u00e7on","year":"2024","journal-title":"Stoch.
