MultipleComparisons

Adjusting a family of p-values for the number of tests in it.

Twenty tests at the five-percent level produce one significant result by chance alone. These three rules answer that, and they answer different questions: Bonferroni controls the chance of any false positive, while the Benjamini rules control the expected proportion of false positives among the results called significant.

Each returns adjusted p-values in the input's own order, so an adjusted value can be compared against the level the caller already had in mind.
