One is the unbiased statistic which is locally optimal for small values of the parameter. Others are Bayes procedures within a class of quadratic statistics for a diffuse prior with different choices of the prior mean. These estimators are compared with the DerSimonian\u2013Laird procedure and the Hedges statistic in particular via the quadratic risk of the treatment effect estimator. A Monte Carlo study supports the usage of confidence intervals derived from the new estimators.<\/jats:p>","DOI":"10.1111\/j.1467-9868.2012.01047.x","type":"journal-article","created":{"date-parts":[[2012,10,12]],"date-time":"2012-10-12T10:30:28Z","timestamp":1350037828000},"page":"451-469","source":"Crossref","is-referenced-by-count":47,"title":["Estimating Heterogeneity Variance in Meta-Analysis"],"prefix":"10.1093","volume":"75","author":[{"given":"Andrew L.","family":"Rukhin","sequence":"first","affiliation":[{"name":"National Institute of Standards and Technology , Gaithersburg , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2012,10,12]]},"reference":[{"key":"2023031303053244300_","doi-asserted-by":"crossref","first-page":"201","DOI":"10.1002\/(SICI)1097-0258(19980130)17:2<201::AID-SIM736>3.0.CO;2-9","article-title":"Approximate Bayes inference for random effects meta-analysis","volume":"17","author":"Abrams","year":"1998","journal-title":"Statist.
