Šidák correction : ウィキペディア英語版 | Šidák correction In statistics, the Šidák correction, or Dunn–Šidák correction, is a method used to counteract the problem of multiple comparisons. It is a simple method to control the familywise error rate that is probabilistically exact when the individual tests are independent from each other, conservative under positive dependence, and liberal under negative dependence. It is credited to a 1967 paper by the statistician and probabilist Zbyněk Šidák. ==Usage==
* Given ''m'' different null hypotheses, each null hypotheses is rejected that has a p-value lower than . * This test produces a familywise Type I error rate of exactly when the tests are independent from each other and all null hypotheses are true. It is less stringent than the Bonferroni correction, but only slightly. For example, for = 0.05 and ''m'' = 10, the Bonferroni-adjusted level is 0.005 and the Šidák-adjusted level is approximately 0.005116. * One can also compute confidence intervals matching the test decision using the Šidák correction by using 100(1 − α)1/''m''% confidence intervals.
