WebAvailable multiple comparison tests are Bonferroni, Tukey's honestly significant difference test, Sidak, Gabriel, Hochberg, Dunnett, Scheffé, and LSD (least significant difference). LSD.

Bonferroni vs tukey post hoc
Did you know?
WebThe Bonferroni is too conservative since it corrects for the worst case (independent comparisons). This makes the hsd the best of this group. It is also worth noting that the Tukey hsd controls the Type I error rate even if you do not due an ANOVA. Ironically, most people call it a post hoc test when it should be planned a priori. Share Cite WebTukey’s Honest Significant Difference (HSD) is a very popular post hoc analysis. This analysis, like Bonferroni’s, makes adjustments based on the number of comparisons, …
WebPost-hoc pairwise comparisons are commonly performed after significant effects when there are three or more levels of a factor. Stata has three built-in pairwise methods ( sidak, bonferroni and scheffe) in the oneway command. Web• Tukey test (recommended) • Bonferroni • Sidak • Holm-Sidak. This test is more powerful than the Tukey method (3), which means that it can sometimes find a statistically significant difference where the Tukey method cannot. This test cannot compute confidence intervals, and for this reason we prefer the Tukey test • Newman-Keuls.
