We term this tree as the Average Linkage Minimum Spanning Tree. We also introduce a technique to associate a value of reliability to the links of correlation-based graphs by using bootstrap replicas of data. Both techniques are applied to the portfolio of the 300 most capitalized stocks traded on the New York Stock Exchange during the time period 2001\u20132003. We show that the Average Linkage Minimum Spanning Tree recognizes economic sectors and sub-sectors as communities in the network slightly better than the Minimum Spanning Tree. We also show that the average reliability of links in the Minimum Spanning Tree is slightly greater than the average reliability of links in the Average Linkage Minimum Spanning Tree. <\/jats:p>","DOI":"10.1142\/s0218127407018415","type":"journal-article","created":{"date-parts":[[2007,9,5]],"date-time":"2007-09-05T10:23:49Z","timestamp":1188987829000},"page":"2319-2329","source":"Crossref","is-referenced-by-count":121,"title":["SPANNING TREES AND BOOTSTRAP RELIABILITY ESTIMATION IN CORRELATION-BASED NETWORKS"],"prefix":"10.1142","volume":"17","author":[{"given":"MICHELE","family":"TUMMINELLO","sequence":"first","affiliation":[{"name":"Dipartimento di Fisica e Tecnologie Relative, Universit\u00e0 di Palermo, Viale delle Scienze, I-90128 Palermo, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CLAUDIA","family":"CORONNELLO","sequence":"additional","affiliation":[{"name":"Dipartimento di Fisica e Tecnologie Relative, Universit\u00e0 di Palermo, Viale delle Scienze, I-90128 Palermo, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"FABRIZIO","family":"LILLO","sequence":"additional","affiliation":[{"name":"Dipartimento di Fisica e Tecnologie Relative, Universit\u00e0 di Palermo, Viale delle Scienze, I-90128 Palermo, Italy"},{"name":"Santa Fe Institute, 1399 Hyde Park Road, Santa Fe, NM 87501, USA"},{"name":"Istituto Nazionale di Fisica Nucleare, Sezione di Catania, Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SALVATORE","family":"MICCICH\u00c8","sequence":"additional","affiliation":[{"name":"Dipartimento di Fisica e Tecnologie Relative, Universit\u00e0 di Palermo, Viale delle Scienze, I-90128 Palermo, Italy"},{"name":"Istituto Nazionale di Fisica Nucleare, Sezione di Catania, Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ROSARIO N.","family":"MANTEGNA","sequence":"additional","affiliation":[{"name":"Dipartimento di Fisica e Tecnologie Relative, Universit\u00e0 di Palermo, Viale delle Scienze, I-90128 Palermo, Italy"},{"name":"Istituto Nazionale di Fisica Nucleare, Sezione di Catania, Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1038\/43601"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1103\/RevModPhys.74.47"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1038\/35000501"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.97.18.10101"},{"key":"rf5","volume-title":"Cluster Analysis for Applications","author":"Anderberg M.
