It states that the variance of a sample scales as some power of the mean of the sample. We study generalizations of Taylor\u2019s law in the context of heavy-tailed distributions with infinite mean and variance. We establish the probabilistic limit and analyze the associated convergence rates. Our results extend the existing literature by relaxing the assumption that the observed random variables are independently and identically distributed to accommodate dependence and heterogeneity among them. This generalization enables application of Taylor\u2019s law to dependent time series and network-structured data. We support the theoretical developments by extensive simulations, and the practical relevance through applications to real network data.<\/jats:p>","DOI":"10.1073\/pnas.2611888123","type":"journal-article","created":{"date-parts":[[2026,10,1]],"date-time":"2026-10-01T16:09:36Z","timestamp":1790870976000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":1,"title":["Generalized Taylor\u2019s law for infinite-mean heavy-tailed data under dependence and heterogeneity"],"prefix":"10.1073","volume":"123","author":[{"given":"Pok Him","family":"Cheng","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00hj8s172","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Statistics, Columbia University","place":["New York"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9746-6725","authenticated-orcid":false,"given":"Joel E.","family":"Cohen","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00hj8s172","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Statistics, Columbia University","place":["New York"]},{"id":[{"id":"https:\/\/ror.org\/0420db125","id-type":"ROR","asserted-by":"publisher"}],"name":"Laboratory of Populations, The Rockefeller University","place":["New York"]},{"id":[{"id":"https:\/\/ror.org\/00hj8s172","id-type":"ROR","asserted-by":"publisher"}],"name":"Climate School, Columbia University","place":["New York"]},{"id":[{"id":"https:\/\/ror.org\/024mw5h28","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Statistics, University of Chicago","place":["Chicago"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hok Kan","family":"Ling","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02y72wh86","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Mathematics and Statistics, Queen\u2019s University","place":["Kingston, Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheung Chi Phillip","family":"Yam","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00t33hh48","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Statistics and Data Science, The Chinese University of Hong Kong","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2026,10,1]]},"reference":[{"key":"e_1_3_4_1_2","volume-title":"Handbook of Heavy Tailed Distributions in Finance: Handbooks in Finance, Book 1","author":"Rachev S.
