What is Hochberg gt2?
a post hoc or multiple comparison test which is used to determine which of three or more means differ from one another in an analysis of variance. It is used with groups which have equal variances. It is based on the studentized maximum modulus rather than the studentized range.
What is Tamhane’s T2 test?
Tamhane’s T2 . Conservative pairwise comparisons test based on a t test. This test is appropriate when the variances are unequal. Dunnett’s T3 .
What are post hoc tests used for?
Post hoc (“after this” in Latin) tests are used to uncover specific differences between three or more group means when an analysis of variance (ANOVA) F test is significant.
Which post hoc test is best for Anova?
The most common post-hoc tests are here number wise from 1 (better) to onwards:
- Fisher’s Least Significant Difference (LSD)
- Holm-Bonferroni Procedure.
- Newman-Keuls.
- Rodger’s Method.
- Scheffé’s Method.
- Tukey’s Test (see also: Studentized Range Distribution)
- Dunnett’s correction.
- Benjamin-Hochberg (BH) procedure.
What is Tamhane’s T2?
Tamhane’s T2 . Conservative pairwise comparisons test based on a t test. This test is appropriate when the variances are unequal. Dunnett’s T3 . Pairwise comparison test based on the Studentized maximum modulus.

Which is an example of Holm and Hochberg’s method?
Example 1: Repeat Example 1 of Bonferroni and Dunn-Sidàk Tests using the Holm’s and Hochberg methods. For these methods, we first rank the p-values of the k tests from smallest to largest p1 ≤ p2 ≤ … ≤ pk.
Which is a non significant result in Hochberg’s test?
In the Hochberg approach, we start from the largest p-value and continue to test until we find the first significant (i.e. pi < α/ (k–i+1)) at which point all smaller pi are considered to be significant. Since p6 =.11542 ≥.05/1 =.05, the result for C is non-significant. Similarly E and D have non-significant results.
Which is the Bonferroni version of Holm and Hochberg’s?
Note too that we have presented the Bonferroni version of the Holm’s and Hochberg’s methods; we could have used a Dunn-Sidàk version of these methods. In this case, we replace α/ (k–i+1) by 1 – (1 – α) 1/ (k–i+1).
