How to get the information of categorical group combinations for "Level of Effect" in General Linear Model result table?

**For example: **General Linear Model Regression: summary of coefficients for between variable effects

What does each "Level of Effect" represent for variable interaction terms? e.g. Level of Effect 1 to 10 for interaction terms of variables gear*carb

How to get the information of categorical group combinations for Level of effects for categorical variable * variable interactions in General Linear Model regression ?

Windows

In the General Linear Model dialog, under "Summary" tab, click on "Design Terms"

This will show the categorical group combinations for each level of effects of the variable interaction term.

For example, in above table,

group "g5" is used as reference group for variable gear and group "c8" is used as reference group for variable carb.

level of effect 1 of the interaction term gear*carb corresponding to column "12" represents gear group "g3" * carb group "c1".

level of effect 2 of the interaction term gear*carb corresponding to column "13" represents gear group "g3" * carb group "c2".

and so on...
