# No Tukey Test on ANOVA package

I'm trying to use the ANOVA package and have mathematica display the Tukey PostTest, but all I get is this:

ANOVA[Tratamientos, PostTests -> Tukey]

ANOVA::nottest: Tukey is not a valid PostTests entry, and will be ignored. Valid PostTests entries are Bonferroni, Tukey, StudentNewmanKeuls, Duncan, and Dunnett. >>


Any advice? Am I missing something?

Hahaha... "Tukey is not a valid PostTests entry, and will be ignored. Valid PostTests entries are Bonferroni, Tukey, ..." –  rm -rf Apr 2 '13 at 15:49
What version are you using? I can't reproduce this back to v.7. –  rcollyer Apr 2 '13 at 16:04
I'm using version 9, also, I'm on linux. –  Cobo Apr 2 '13 at 17:40
Can't reproduce on Win7-64, either v9 or v8. The exact error message is generated if you enter the option value as the string "Tukey" instead of the symbol Tukey. Might that have been the case here? –  Sjoerd C. de Vries Apr 2 '13 at 19:02

Seems to work here (Mathematica 8.0):

Needs["ANOVA"]
ANOVA[{{1, 1}, {1, 2}, {2, 15}, {2, 20}}, PostTests -> Tukey]

I'm using Mathematica 9, so maybe thats the problem? Also, I'm on linux. –  Cobo Apr 2 '13 at 17:40
@Cobo it works on v. 9 as well (at least on my Mac) –  cormullion Apr 2 '13 at 17:43
@Cobo Also runs here on MMa 9 (Windows 8). Maybe the problem is on the data? Are you sure the data input is in the correct form? –  Sosi Apr 2 '13 at 17:47
