When one can define (possibly several) such partitions, it may be desirable to control the group FDR simultaneously for all partitions (as special cases, the \u2018finest\u2019 partition divides the n hypotheses into n groups of one hypothesis each, and this corresponds to controlling the usual notion of FDR, whereas the \u2018coarsest\u2019 partition puts all n hypotheses into a single group, and this corresponds to testing the global null hypothesis). We introduce the p-filter, which takes as input a list of n p-values and M \u2a7e 1 partitions of hypotheses, and produces as output a list of n or fewer discoveries such that the group FDR is provably simultaneously controlled for all partitions. Importantly, since the partitions are arbitrary, our procedure can also handle multiple partitions which are non-hierarchical. The p-filter generalizes two classical procedures\u2014when M = 1, choosing the finest partition into n singletons, we exactly recover the Benjamini\u2013Hochberg procedure, whereas, choosing instead the coarsest partition with a single group of size n, we exactly recover the Simes test for the global null hypothesis. We verify our findings with simulations that show how this technique can not only lead to the aforementioned multilayer FDR control but also lead to improved precision of rejected hypotheses. We present some illustrative results from an application to a neuroscience problem with functional magnetic resonance imaging data, where hypotheses are explicitly grouped according to predefined regions of interest in the brain, thus allowing the scientist to employ field-specific prior knowledge explicitly and flexibly.<\/jats:p>","DOI":"10.1111\/rssb.12218","type":"journal-article","created":{"date-parts":[[2016,11,21]],"date-time":"2016-11-21T04:06:42Z","timestamp":1479701202000},"page":"1247-1268","source":"Crossref","is-referenced-by-count":44,"title":["The<i>p<\/i>-filter: Multilayer False Discovery Rate Control for Grouped Hypotheses"],"prefix":"10.1093","volume":"79","author":[{"given":"Rina Foygel","family":"Barber","sequence":"first","affiliation":[{"name":"University of Chicago \u00a0 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aaditya","family":"Ramdas","sequence":"additional","affiliation":[{"name":"University of California at Berkeley \u00a0 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2016,11,20]]},"reference":[{"key":"2023021709330841200_rssb12218-cit-0001","doi-asserted-by":"crossref","first-page":"297","DOI":"10.1111\/rssb.12028","article-title":"Selective inference on multiple families of hypotheses","volume":"76","author":"Benjamini","year":"2014","journal-title":"J.
