WebMar 21, 2024 · One measure that provides an estimation of the number of false positives in an analysis is the false discovery rate (FDR). The FDR was first introduced as a control measure for high-throughput data in biology ( Benjamini & Hochberg, 1995 ) and is defined as the expected ratio of false positive (FP) classifications (false discoveries) to the ...
