http://rcompanion.org/rcompanion/f_01.html WebGenetic association tests involving copy-number variants (CNVs) are complicated by the fact that CNVs span multiple markers at which measurements are taken. The power of an association test at a single marker is typically low, and it is desirable to pool information across the markers spanned by the CNV. However, CNV boundaries are not known in …

WebSep 7, 2024 · The FWER is the probability of making at least one false discovery (type 1 error) among the entire set of hypotheses when multiple testing. In contrast, the FDR is the expected proportion of false discoveries as a fraction the number of null hypothesis rejected among a set of hypotheses. WebSep 5, 2011 · False Discovery Rate: Corrected & Adjusted P-values Posted on 05.September.2011 Until mid-1990’s, control of the error rate under multiple testing was done, in general, using family-wise error rate (FWER). An example of this kind of correction is the Bonferroni correction.
