Balancing Type I Risk and Loss of Power in Ordered Bonferroni Procedures.
de Cani, John S.
Journal of Educational Psychology, v76 n6 p1035-37 Dec 1984
While Bonferroni procedures control the risk of Type I errors, their cost is loss of power. Ordered Bonferroni procedures conserve power for more important tests while sacrificing power for less important tests. Both costs and benefits should be considered when choosing weights for individual tests and the overall level of Type I error protection. (Author/BS)
