A More Robust Procedure for Testing the Null Hypothesis in MANOVA
by Chris N. Kladopoulos and Philip H. Ramsey.
Abstract:
Earlier research on Pillai's V statistic and Wilks' generalized correlation ratio statistic, U, suggest that a combination of these two procedures can be used to form a more robust test in MANOVA. The present investigation considers two methods of forming such a composite procedure. One of these procedures is shown to provide a robust alternative to existing methods for testing the full-null hypothesis for small samples while the other is shown to be superior for medium to large samples.
Key Words:
