A question about Tukey test

PsycResearcher — Fri, 26 Aug 2011 18:20:08 GMT

Hi all,

When doing Tukey's HSD, SPSS gives the results of a homogeneous subset (ie., categorizing different groups into different subsets). Just wonder if the same analyses can be done in SAS? If so, how to write the syntax for this?

Thanks,

Chester

I'm not certain, but I think you are looking for the LINES option. Take a look at: http://udel.edu/~mcdonald/statanovaunplanned.html

Yes. proc glm can do it. If you want "multi-compare".

But I am not sure whether it is you find.

Hi Ksharp,

I am not sure what is "multi-compare". What I want is "homogeneous subsets", which look like the last table in the webpage:

http://webpub.allegheny.edu/dept/psych/SPSS/SPSS1bANOVA.html

The reason I ask for this kind of output is that I encountered the situation like this: I have five groups of people (A, B, C, D, and E). B differ from every other group. A does not differ from C, D, and E. However, C differ from D and E, and D do not differ from E. I have lots of analysis results like this, and found it extremely difficult to report them. Therefore, if I can use homogeneous subset (or other possible solutions) then that will be useful.

To art297: I will try your method and see if it works! Thanks!

Yes. If it were ANOVA. The more information please check the documentation about proc glm.

proc glm;

class A B;

model Y=A B A*B;

means A B / tukey;

means A*B;

run;
