In an estimation problem, the aim is only to determine how many individuals are infected instead of determining who is infected (classification problem). In that setting, our goal was to compare the performance of using one or two-dimensional arrays. The best performance was established according to one of the following criteria: minimizing the number of individuals or the number of tests required to attain a certain estimate accuracy. It is observed that when we want to minimize the number of individuals used, the two-dimensional procedures have a little advantage over the one-dimensional procedures. However, when the major concern is the cost, the one-dimensional procedures clearly outperform the two-dimensional procedures.<\/jats:p>","DOI":"10.1088\/1742-6596\/1564\/1\/012028","type":"journal-article","created":{"date-parts":[[2020,6,30]],"date-time":"2020-06-30T00:14:14Z","timestamp":1593476054000},"page":"012028","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Estimation of prevalence in rare disease using pooled samples"],"prefix":"10.1088","volume":"1564","author":[{"given":"J P","family":"Martins","sequence":"first","affiliation":[]},{"given":"R","family":"Santos","sequence":"additional","affiliation":[]},{"given":"M","family":"Felgueiras","sequence":"additional","affiliation":[]}],"member":"266","reference":[{"key":"JPCS_1564_1_012028bib1","doi-asserted-by":"crossref","first-page":"436","DOI":"10.1214\/aoms\/1177731363","article-title":"The detection of defective members in large populations","volume":"14","author":"Dorfman","year":"1943","journal-title":"Ann.
