Power and Type I Error Rates of New Pairwise Multiple Comparison Procedures under Heterogeneous Variances.

Kromrey, Jeffrey D.; La Rocca, Michela A.

Journal of Experimental Education, v63 n4 p343-62 Sum 1995

The Type I error rates and statistical power of nine selected multiple comparison procedures were compared in a Monte Carlo study. The Peretz, Ryan, and Fisher-Hayter tests were the most powerful, and differences among these procedures were consistently small. Choosing among these procedures might be based on their calculational complexity. (SLD)
