Power of pairwise comparisons in the equal variance and unequal sample size case.

A Monte Carlo simulation was conducted to compare five, pairwise multiple comparison procedures. The number of means varied from 4 to 6 and the sample size ratio varied from 1 to 60. Procedures were evaluated on the basis of Type I errors, any-pair power and all-pairs power.

Power and Type I errors for pairwise comparisons of means in the unequal variances case.

A Monte Carlo simulation was conducted to compare pairwise multiple comparison procedures. The number of means varied from 4 to 8 and the sample sizes varied from 2 to 500. Procedures were evaluated on the basis of Type I errors, any-pair power and all-pairs power.
