Nettet30. jan. 2016 · We presented an efficient algorithm to apply correctly the Benjamini–Hochberg Linear Step Up FDR controlling procedure in a huge-scale testing problem. Since we have shown that our algorithm requires only linear time, our algorithm is provably not any more computationally burdensome than even using a rigid Bonferroni … Using a multiplicity procedure that controls the FDR criterion is adaptive and scalable. Meaning that controlling the FDR can be very permissive (if the data justify it), or conservative (acting close to control of FWER for sparse problem) - all depending on the number of hypotheses tested and the level of significance. The FDR criterion adapts so that the same number of false discoveries (V) will have different im…
