JMP 9.0 ANOM vs ANOVA

Oct 27, 2010 05:16 PM (4540 views)
Anyone know what the difference is between Analysis of Means and ANOVA besides the obvious graphical displays? I like the ANOM feature, but are there any other advantages of the ANOM over the ANOVA (with assocaited p-values and means comparison tests)? Thanks!

ANOM compares the group mean to the overall mean, where ANOVA compares the group mean to the other group means. ANOVA can tell you if there is a significant difference, while ANOM can tell which group mean is significantly different.

The SAS documentation on PROC ANOM has better discussion than I can provide:
