The challenge is to adjust for the selection of subsets of variables having linear combinations with maximal sample correlation. To this end, we construct a stabilized one-step estimator of the Euclidean norm of the canonical correlations maximized over subsets of variables of prespecified cardinality. This estimator is shown to be consistent for its target parameter and asymptotically normal, provided the dimensions of the variables do not grow too quickly with sample size. We also develop a greedy search algorithm to accurately compute the estimator, leading to a computationally tractable omnibus test for the global null hypothesis that there are no linear relationships between any subsets of variables having the prespecified cardinality. We further develop a confidence interval that takes the variable selection into account.<\/jats:p>","DOI":"10.1093\/biomet\/asab059","type":"journal-article","created":{"date-parts":[[2021,11,13]],"date-time":"2021-11-13T12:08:51Z","timestamp":1636805331000},"page":"1067-1083","source":"Crossref","is-referenced-by-count":4,"title":["Significance testing for canonical correlation analysis in high dimensions"],"prefix":"10.1093","volume":"109","author":[{"given":"Ian W","family":"McKeague","sequence":"first","affiliation":[{"name":"Department of Biostatistics, Columbia University , Room R639, 722 West 168th Street, New York, New York 10032, U.S.A"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Statistics, Florida State University , 214 OSB, 117 N.
