Šidák correction
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. WebApr 22, 2014 · The idea behind the shortcut is to consider only the “worst” (the smallest) test statistic in the subsets of the same cardinality. Note that, for both the Šidák correction-based test and the Fisher test, the values of the test statistics are monotonically decreasing among intersection hypotheses of the same size.
