Hochberg step-up procedure

NettetTo control for typeⅠerrors, false discovery rate (FDR) correction for multiple comparisons was applied using Benjamini-Hochberg step-up procedure, the mean FDR α. 43 For effect sizes, Cohen’s d, Phi, η 2, and η 2 p were calculated for t-test, χ 2 test, Mann–Whitney U-test, and rANOVA, respectively. Ethics Statement NettetPROC MULTTEST provides the following stepwise p -value adjustments: step-down Bonferroni (Holm), step-down Šidák, step-down bootstrap and permutation resampling, Hochberg’s ( 1988) step-up, Hommel’s ( 1988 ), and Fisher’s combination method.

Moreover, since the step-up procedure rejects any hypothesis rejected by the step-down procedure, it is more powerful irrespective of the measure of power. However, one minor shortcoming even with the speci c constants (2) is that there is no universal assurance that the FWE is controlled with the step-up (Hochberg) procedure.

We list these p-values in ascending order and denote them by . A procedure that goes from a small p-value to a large one will be called a step-up procedure. In a similar way, in a "step-down" procedure we move from a large corresponding test statistic to a smaller one.
