Scheffe's More Powerful F-Protected Post Hoc Procedure.
Klockars, Alan J.; Hancock, Gregory R.
Journal of Educational and Behavioral Statistics, v25 n1 p13-19 Spr 2000
Describes a more powerful version of Scheffe's post hoc multiple comparison procedure with its original derivation (H. Scheffe, 1970). Shows that a more liberal critical value assuming k - 2 between-group degrees of freedom may be used if an omnibus null hypothesis across all groups has been rejected. (Author/SLD)
