# Interpretation Estimates of fixed effects, redundant parameters

I am doing multi level analysis with SPSS and have some categorical variables as control variables (country, gender).

As you can see country has a significant effect, but I am not sure how I can report it sufficiently with country 3 being set to zero because it is redundant.

Basically I want to make a table which includes Estimates, Standard error and significance. Can I somehow put country as one variable?

• Check footnote b... SPSS adds the reference class to the output (which is represented by the intercept and is thus redundant, i.e. getting an effect of 0). – Michael M Jul 13 '17 at 10:36

Redendant levels are most often called reference levels you can just replace 0's in Estimate column with reference level note or change description of non-refrence levels e.g. [country=1 vs 3] or make another footnote under your table saying "Reference levels: country=3, gender=1".
You can get significance of country as one variable. You can't get Estimate and Std. error for it. Why? Just take a look on Estimate's interpretation. 1.07 for country=1 means that in this country OC_A_Total is on average 1.07 units higher than in reference country (country=3), adjusting for age, gender and the rest of your variables, of course. Similarly, you can say, that in country=2 it is 1.005 units higher. These two estimates can not be collapsed into one (at least if you still wish it to have some clear interpretation).
