To overcome these challenges, we propose a semiparametric approach to sparse canonical correlation analysis based on the Gaussian copula. The main result of this paper is a truncated latent Gaussian copula model for data with excess zeros, which allows us to derive a rank-based estimator of the latent correlation matrix for mixed variable types without estimation of marginal transformation functions. The resulting canonical correlation analysis method works well in high-dimensional settings, as demonstrated via numerical studies, and when applied to the analysis of association between gene expression and microRNA data from breast cancer patients.<\/jats:p>","DOI":"10.1093\/biomet\/asaa007","type":"journal-article","created":{"date-parts":[[2020,2,4]],"date-time":"2020-02-04T23:30:43Z","timestamp":1580859043000},"page":"609-625","source":"Crossref","is-referenced-by-count":33,"title":["Sparse semiparametric canonical correlation analysis for data of mixed types"],"prefix":"10.1093","volume":"107","author":[{"given":"Grace","family":"Yoon","sequence":"first","affiliation":[{"name":"Department of Statistics, Texas A&M University, College Station, Texas 77843, U.S.A"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raymond J","family":"Carroll","sequence":"additional","affiliation":[{"name":"Department of Statistics, Texas A&M University, College Station, Texas 77843, U.S.A"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irina","family":"Gaynanova","sequence":"additional","affiliation":[{"name":"Department of Statistics, Texas A&M University, College Station, Texas 77843, U.S.A"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,4,15]]},"reference":[{"key":"2020081714265548700_B1","doi-asserted-by":"crossref","first-page":"1287","DOI":"10.1016\/j.molonc.2015.03.001","article-title":"MicroRNA-135b regulates ER$\\alpha$, AR and HIF1AN and affects breast and prostate cancer cell growth","volume":"9","author":"Aakula,","year":"2015","journal-title":"Molec.
