comparing a group to average of all others

[Nico Peruzzi]

Hello Listers,

I have a numeric DV, and 7 groups, and want to do a post-hoc comparison
wherein 1 of the groups is compared to the average of the remaining groups.

I'm in v 13.0 and have sorted through some options under Post Hoc in ANOVA,
and can't quote seem to come up with it.

Does such a comparison option exist?  If not, does someone have a compute
statement handy that I could borrow from to create the comparison?

Thanks in advance, Nico

Hi Nico

Use HELMERT contrasts (UNIANOVA). From the online help: "Helmert
contrasts: Each level of the factor except the last is compared to the
mean of subsequent levels." Code your grouping variable so that the
group you want to compare with the rest is the first, and then the first
HELMERT contrast will give you the comparison you want.

HTH,

Hi list,

I would like to run an spss production facility file in DOS mode. The DOS code is easy, e.g.:
"c:\progra~1\spss\spssprod.exe" "d:\test.spp" -s

But can I also embed any user prompts (the ones that start with an @-sign in the sps syntax) in this DOS code? I would like to run an identical syntax on a whole bunch of directories. Here's the pseudo code:
"c:\progra~1\spss\spssprod.exe" "d:\test.spp" "out1" -s -yes
"c:\progra~1\spss\spssprod.exe" "d:\test.spp" "out2" -s -yes
"c:\progra~1\spss\spssprod.exe" "d:\test.spp" "out3" -s -yes
('-yes' to indicate the the out argument should be quoted).

The contents of the associated sps file could start with:
get file = 'd:\temp\' + @out_dir + 'somefile.sav'.


Is this possible?

Thanks in advance!

Cheers!
Albert-Jan
