WebMay 2, 2014 · Specifically, under the Bonferroni correction, α * is the result of α/IJ; under the Šidák correction, α * is the result of 1 − (1 − α) 1/IJ. Note that the values for α * are identical for 3 × 4 tables (left panel) and 2 × 6 tables ( center panel ) under either correction, since the relation is determined only by the overall number of cells. The Šidák correction is derived by assuming that the individual tests are independent.Let the significance threshold for each test be ; then the probability that at least one of the tests is significant under this threshold is (1 - the probability that none of them are significant).Since it is assumed that they are … See more In statistics, the Šidák correction, or Dunn–Šidák correction, is a method used to counteract the problem of multiple comparisons.

In some cases, the number of sequences, , increase as the data size of each sequences, , increase. In particular, suppose . If this is true, then we will need to test a null including infinitely many hypotheses, that is To design a test, Šidák correction may be applied, as in the case of finitely many t-test. However, when , the Šidák correction for t-test may not achieve the level we want, that is, the true level of t…
