Dec 3, 2021 · The Scheffe Method. The Scheffe method is the most conservative post-hoc pairwise comparison method and produces the widest confidence intervals when comparing group means. We can use the ScheffeTest() function from the DescTools package to perform the Scheffe post-hoc method in R: Before performing the pairwise p-test, here is a boxplot illustrating the differences across the three groups: Source: RStudio Output From a visual glance, we can see that the mean ADR across the Direct and TA/TO distribution channels is higher than that of Corporate, and the dispersion across ADR is significantly greater.Pairwise mean comparisons can be thought of as a subset of possible contrasts among the means. If only pairwise comparisons are made, the Tukey method will produce the narrowest confidence intervals and is the recommended method. The Bonferroni and Scheffé methods are used for general tests of possible contrasts. Pairwise comparison is a key ingredient in multi-criteria decision analysis. The method is based on a set of comparisons conducted by a group of experts, comparing all possible pairs of alternatives involved in the decision process. The outcome is the estimation of weights determining the ranking of alternatives.
