Without making parametric assumptions on the component distributions, we investigate how one can identify the number of components from the distribution function of the observed data. When k\u2a7e2, a lower bound on the number of components (M) is non-parametrically identifiable from the rank of a matrix constructed from the distribution function of the observed variables. Building on this identification condition, we develop a procedure to estimate a lower bound on the number of components consistently.<\/jats:p>","DOI":"10.1111\/rssb.12022","type":"journal-article","created":{"date-parts":[[2013,7,3]],"date-time":"2013-07-03T05:16:43Z","timestamp":1372828603000},"page":"97-111","source":"Crossref","is-referenced-by-count":51,"title":["Non-Parametric Identification and Estimation of the Number of Components in Multivariate Mixtures"],"prefix":"10.1093","volume":"76","author":[{"given":"Hiroyuki","family":"Kasahara","sequence":"first","affiliation":[{"name":"University of British Columbia , Vancouver , Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katsumi","family":"Shimotsu","sequence":"additional","affiliation":[{"name":"University of Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2013,7,3]]},"reference":[{"key":"2023031306053723700_","doi-asserted-by":"crossref","first-page":"3099","DOI":"10.1214\/09-AOS689","article-title":"Identifiability of parameters in latent structure models with many observed variables","volume":"37","author":"Allman","year":"2009","journal-title":"Ann.
