However, within those six, the pairwise method favored higher-dimensional solutions than did SpAM. Thus, SpAM is not uniformly worse than the pairwise method in recovering higher-dimensional spaces.

Bonferroni Method. Bonferroni method for \(g\) comparisons – use \(\alpha / g\)instead of \(\alpha\) for testing each of the \(g\) comparisons. Comparing the Bonferroni Procedure with the Fishers LSD. Fishers’s LSD method is an alternative to other pairwise comparison methods (for post ANOVA analysis).

The pairwise comparisons method considers head-to-head comparisons between all pairs of choices. The choice with the most head-to-head wins is declared the winner with this method. If there is a choice that is preferred in every such pairwise comparison, that choice is called the Condorcet Winner (or Condorcet Candidate).

Tukey's method. Tukey's method considers all possible pairwise differences of means at the same time. The Tukey method applies simultaneously to the set of all pairwise comparisons. {μi −μj}.
