False discovery rates in biological networks
WebTo control the false positives amongst a set of accepted matches, there is a need for some statistical estimate that can reflect the amount of false positives present in the data processed. False discovery rate (FDR) is the metric for global confidence assessment of a large-scale proteomics dataset. This chapter covers the basics of FDR, its ...

WebRecall that a p-value of 0.0101 implies a 1.01% chance of false positives, and so with 3516 compounds, we expect about 36 false positives, i.e. 3516 × 0.0101 = 35.51. In this experiment, there are 800 compounds with a value of 0.0101 or less, and so 36 of these will be false positives.
