ANOVA 2-way all subgroup combinations

[Silvertreetops]

Hello - I am wanting to do 2-way ANOVA tests in SAS. I am having trouble getting results against all the subgroups I want to.

It is best explained by the dummy data file I created (attached).

I want to see ANOVA results of all 'Size' and 'Industry' group combinations. So for example the subgroups from the dummy data file (attached) should be:

1. Size 1-2, Industry a
2. Size 1-2, Industry b
3. Size 3-4, Industry a
4. Size 3-4, Industry b

When I run the PROC GLS function I can get results for 'Size' vs 'Industry', but not for each of the subgroups.

I would really appreciate guidance here.

Regards,

Sivlertreetops

I don't know SAS very well, but what are you looking for is "post hoc analysis" or "multiple comparison tests", examples are the "Tukey test" or the "Bonferroni test".

Do you mean PROC GLM?
