Related Error Rates
The discovery of the FDR was preceded and followed by many other types of error rates. These include:
- (per-comparison error rate) is defined as: . Testing individually each hypothesis at level guarantees that (this is testing without any correction for multiplicity)
- (the family wise error rate, in the weak sense) is defined as: . There are numerous procedures that control the FWER.
- (the family wise error rate, in the strong sense) is defined as: . There are numerous procedures that control the FWER.
- (The tail probability of the False Discovery Proportion), suggested by Lehmann and Romano, van der Laan at al, is defined as: .
- (Suggested by Sarker) is defined as: .
- is the proportion of false discoveries amound the discoveries", suggested by Soric in 1989, and is defined as: . This is a mixture of expectations and realizations, and has the problem of control for .
- (or Fdr) was used by Benjamini and Hochberg, and later called "Fdr" by Efron (2008) and earlier. It is defined as: . Controlling this error rate does not provide a weak control of the FWER.
- (or pFDR) was used by Benjamini and Hochberg, and later called "pFDR" by Storey (2002). It is defined as: . Controlling this error rate does not provide a weak control of the FWER.
- is defined as:
- The local fdr is defined as:
- False exceedance rate (the tail probability of FDP), defined as:
- (Weighted FDR). Associated with each hypothesis i is a weight, the weights capture importance/price. The W-FDR is defined as: .
- (False Discovery Cost Rate). Stemming from statistical process control: associated with each hypothesis i is a cost and with the intersection hypothesis a cost . The motivation is that stopping a production process may incur a fixed cost. It is defined as:
- (per-family error rate), at level, is defined as: .
- (False Non-Discovery Rates) by Sarkar; Genovese and Wasserman is define as:

Famous quotes containing the words related, error and/or rates:
“So universal and widely related is any transcendent moral greatness, and so nearly identical with greatness everywhere and in every age,—as a pyramid contracts the nearer you approach its apex,—that, when I look over my commonplace-book of poetry, I find that the best of it is oftenest applicable, in part or wholly, to the case of Captain Brown.”
—Henry David Thoreau (1817–1862)
“They have their belief, these poor Tibet people, that Providence sends down always an Incarnation of Himself into every generation. At bottom some belief in a kind of pope! At bottom still better, a belief that there is a Greatest Man; that he is discoverable; that, once discovered, we ought to treat him with an obedience which knows no bounds. This is the truth of Grand Lamaism; the “discoverability” is the only error here.”
—Thomas Carlyle (1795–1881)
“Families suffered badly under industrialization, but they survived, and the lives of men, women, and children improved. Children, once marginal and exploited figures, have moved to a position of greater protection and respect,... The historic decline in the overall death rates for children is an astonishing social fact, notwithstanding the disgraceful infant mortality figures for the poor and minorities. Like the decline in death from childbirth for women, this is a stunning achievement.”
—Joseph Featherstone (20th century)
