Tukey HSD pairwise comparisons of group means (Tukey–Kramer standard error for unequal sizes).
p-values and simultaneous confidence intervals use the studentized range with the ANOVA error
degrees of freedom; letters is Minitab-style grouping information (groups sharing a letter are
not significantly different at alpha).
