In the framework of estimating procedures based on the marginal distribution of the P-values without any assumption on gene expression changes, estimators of the FDR are necessarily conservatively biased. Indeed, only an upper bound estimate can be obtained for the key quantity \u03c00, which is the probability for a gene to be unmodified. In this paper, we propose a novel family of estimators for \u03c00 that allows the calculation of FDR.<\/jats:p>\n               <jats:p>Results: The very simple method for estimating \u03c00 called LBE (Location Based Estimator) is presented together with results on its variability. Simulation results indicate that the proposed estimator performs well in finite sample and has the best mean square error in most of the cases as compared with the procedures QVALUE, BUM and SPLOSH. The different procedures are then applied to real datasets.<\/jats:p>\n               <jats:p>Availability: The R function LBE is available at http:\/\/ifr69.vjf.inserm.fr\/lbe<\/jats:p>\n               <jats:p>Contact: \u00a0broet@vjf.inserm.fr<\/jats:p>","DOI":"10.1093\/bioinformatics\/bti063","type":"journal-article","created":{"date-parts":[[2004,10,13]],"date-time":"2004-10-13T01:32:31Z","timestamp":1097631151000},"page":"660-668","source":"Crossref","is-referenced-by-count":89,"title":["A simple procedure for estimating the false discovery rate"],"prefix":"10.1093","volume":"21","author":[{"given":"Cyril","family":"Dalmasso","sequence":"first","affiliation":[{"name":"INSERM U472, Facult\u00e9 de M\u00e9decine Paris-Sud 16 Avenue Paul Vaillant-Couturier, 94807 Villejuif Cedex, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Bro\u00ebt","sequence":"additional","affiliation":[{"name":"INSERM U472, Facult\u00e9 de M\u00e9decine Paris-Sud 16 Avenue Paul Vaillant-Couturier, 94807 Villejuif Cedex, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thierry","family":"Moreau","sequence":"additional","affiliation":[{"name":"INSERM U472, Facult\u00e9 de M\u00e9decine Paris-Sud 16 Avenue Paul Vaillant-Couturier, 94807 Villejuif Cedex, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2004,10,12]]},"reference":[{"key":"2023013107211875700_B1","unstructured":"Benjamini, Y. and Hochberg, Y. 1995Controlling the false discovery rate: a practical and powerful approach to multiple testing.
